Method The "night-night" method mega thread.

[caribpilgrim]

This is my preferred method to ctb but I have been so far been unable to go unconscious and stay so. Based on feedback from other forum members it seems we are all having similar issues with what should be a simple method. The theory and practical experience with carotid compression indicate that this method should work. So I took a few days off and came back with a clear mind and I think I found an issue we are missing and a practical solution. I am going to document my thinking in the hopes that it would benefit others and that someone might think of ways to more effectively implement this method.

Here are my GOALS with this method:

• Painless
  • The greatest potential source of pain in this method is pressure on the windpipe. At all costs you should keep the windpipe free of obstruction.
• Simple
  • I believe each human has the right to leave this world on their own terms and should have a simple method to achieve this.
  • The main goal is to as much as possible fully occlude the carotid arteries on both sides of the neck. If this is not achieved this method will never work. The Peaceful Pill 2019 edition speaks of targeting the baroreceptors. I believe that is a false trail and insufficient to induce unconsciousness.
  • Why is it so hard to occlude the carotids?
    • Surrounded by connective tissue and muscles.
    • Deep next to the windpipe.
    • The one issue I think we have been missing. We have to keep the chin up to bring the carotids as close as possible to the surface.
  • Solution. The solution I came up with attempts to do three things:
    • Ensure no pressure is applied to the windpipe.
    • Maximal pressure is applied to the carotids.
    • Keep the chin up as the pressure is applied.
      To achieve all of this I used 2 L-shaped pieces of styrofoam 1 inch thick placed on either side of the windpipe. You will have to adjust the height of the L so that it touches the collar bone. This will ensure that it remains locked in place and does not move during the ratchet tightening.
      
      Feedback would be appreciated.

The trick with the chin up is definitely worth a try, different anatomies bring up different problems of course, but the solution is worth a try.
I'm also thinking that by doing it lying down without a pillow, you can get your chin up as your neck is resting either on the ratchet or a shirt (or small pillow). From there you could achieve it lying (in theory).
I also noticed it was actually easier for me to achieve unconsciousness by being sitting rather than lying down (altough both seem to work).

My problem is that said unconsciousness is only achieved with pressure from my fingers, it's super easy to do for me and I blackout within 10 seconds. Problem being that once unconscious, there is no more pressure and nothing to hold it there.
I've tried partial hanging, but it has the same problem, uncomfortable and I just don't pass out. I was thinking that with the "night-night" method, I could redo a scenario similar to my fingers but without pressure drop. I've been trying with two kinesiotapes roles (https://www.google.com/search?q=str...AUIESgB&biw=1920&bih=955#imgrc=u7u0aqfw_1FWcM:) but to not avail.

Anyone would have an idea of an object that would redo the fine pressure of my fingers?

Man, you can read through the thread of all the things I tried. I woke up twice after passing out. In addition, I cannot consistently go unconscious. I don't know what else to try. I think this method will eventually work but there are a lot of variables that I don't feel I have a grip of.

Haven't read the entire thread yet, altough if you're able to get unconscious, you got the biggest hurlde done I believe. I'll read the rest later and say something smart if I have happen to have something to say.
I also just realized that a good way to imitate finger when using ratchets are marbles. I'll see what I can do with that and report.

hi, I'm going to do this tonight. If I fail, would I become a vegetable or have long term consequences? I'm aiming not to fail but if I do, I want to be sure no damages would occur so I can try again.

Thanks!

The possibility is there but more so if you are found before dead, if it fails completely you will not pass out or wake up somewhat quickly after theoretically without damage. There is almost always a risk though so dont take my word for it

I designed a 3D-printable device inspired by the Korean method.

View attachment 13413View attachment 13414View attachment 13415

It took a few iterations but I found the correct placement of the threaded rods thanks to the knowledge shared here.
At first try the feeling was different than manually pressing on the baroreceptors. Probably just bad placement of the collar but I have confidence in this kind of devices. This is the perfect way to go.
Unfortunately the design is rigid and only works for my neck. Flexibility would be one step forward.

Hello

Can you send me the formula for this device for the 3D printer so that I can adjust for my neck size please?

 

[Ixtabba]

Thank you from the bottom of my heart for this method. I cannot wait to practice, if I accidentally ctb... oops. But I would want that anyway and would prefer that to panic.

 

[Mindopali]

2bearcolossus
I second Lisa, can you send the schematics? It looks like a good starting point to test with and apply changes where needed to each and everyone's neck.

 

[Invisible 73]

I tried to find the right spot when I was just in the hospital and couldnt. Can someine help me with locating the right arteries? The diagram isnt helping me. Plus it wasnt available when I was in my inpatient hold

 

[Mindopali]

Invisible 73
I presume you're talking about the right spot with your fingers?
If so: as someone pointed out earlier, your index and thumb are the ones feeling the pulse on the side of your neck. A good starting point is to make an L with your index and thumb, lay your hand sideways on your adam's apple/middle of throat so that these two fingers are laying on the skin. From there, you can tip-toe your way until you can feel your pulse.
There comes the everyone's different part, you will feel the pulse, but sometimes not strongly. It happens, doesn't mean it won't work. Just palp to find where your pulse is the strongest, it's a good starting point.

Now to pass out with your own fingers: It's trial and error. It's a bit easier if you start where you feel the pulse the strongest. The way you plant your fingers is important, the pressure applied less so.

I'll give you my exemple. I thought I couldn't find it, after having tried a lot of times. Then, sitting on a chair, I randomly tried and passed out, and thus had my point. So don't despair, it can take time, but everyone can get strangled, you too. In my case, it's on the same level as my adam's apple, is easier to do when I'm sitting than laying, and with my fingers I have to dig and push a bit to get the cartilage and muscles out of the way. Once it's done, a bit of pressure and I feel my heartbeat slowing in my throat, that's the signal for me that it works. ten seconds later my vision goes black.

For you to find it, these are all things to try, where to apply your fingers, how to "dig them in", your body position with chin up/down or middle and sitting or laying, I also noticed for me that it's much easir if I turn my head slightly to the right.

That's all I can say to find the sweet spot, if there are other tricks my ears are open. Once you have that spot, it'll give you a general idea on where to place ratchet and objects to achieve the effect.
Next time I'm alone, I'll try ratchet plus marble to imitate fingers a bit, see how that works.

When attempting to find my sweet spot i have an uncontrollable urge to cough? What am i doing wrong?

 

[NotOfThisEarth]

Hey everyone,

Been talking to a lot of people in the chat and trying to explain this method, and one user wanted me to make a post about it, so here goes everything.

We're going after a classic idea of using a blood choke, except, it will be against ourselves. In the privacy of our own homes. In a fully relaxed state.

This method is fully capable and will kill you very fast. I know this because it's what we were taught in the Marine Corps.

First, you're going to want some Gorilla tape OR a tree ratchet.

Second, get two Sackhole/Cornhole bags.

Now, depending on what you're using, you'll want to lie on the ground and put the bags on these two exact areas on your neck (In blue).

The reason we're lying on the ground is that we want to be able not to have to fuss over putting the bags on us and making sure they don't fall out of place before we use the ratchet or the tape. You're putting the bags on these two areas to go after the internal carotid arteries.

Start cinching the ratchet closed or wrap the tape around your neck once. Is everything feeling good? I'm glad. If not, then uncinch it a little and place the bags. You want to make sure that you're not compressing the windpipe as that could cause you to freak out a little.

We want this to be painless and fast.

After you're comfortable, sit down if you want to or stand up. Do whatever you want honestly. Start wrapping the tape around your neck more and a little tighter or start closing the ratchet more.

In about 5-20 seconds you will pass out. After that, it's pretty much game over unless you somehow hit the ratchet release. That's why I said we could also use tape as well. With the gorilla tape, it will make sure that you don't inadvertently try to tear the tap off... because it will be strong as hell around your neck.

After you pass out, it will only take a few minutes, and you will be brain dead from the complete lack of blood flow to your brain.

I think I've explained this pretty well and I hope you guys understand the method. If not, please don't hesitate and I'm sure that I can help you out or someone else in the community can help you out.

 

[Mindopali]

Some people have that (I do too), sometimes I can push trough it, sometimes not. But it's not a sign that you're doing it wrong. You can try to inhale deeply beforehand, and another trick is to try another spot, the sensibility is not the same. To pass out with my fingers, using the fingertips tends to be less uncomfortable than the flat part, for me at least.

Here are the design files for the machine: https://gofile.io/?c=9yVZRl

https://sanctioned-suicide.net/attachments/img_20190712_121857_02-jpg.13412/

SolidWorks 2018 is needed to edit the files. Neutral STL-files are also in the .zip, but they are harder to modify. The angle at which the rods are moving should be the same for everyone, only the distance should be personalized.
There's two kind of base part, female and male, considering the extra space needed for the Adam's apple. The male-version works for everyone.
The threads on the rods are right/left handed so the motion when tightening them is "simple". One hand does a clockwise motion, the other counter-clockwise.

Be aware that this device very much could be lethal using little to no effort. I feel uneasy sharing this knowing someone will CTB indirectly through my efforts.

I found my sweet spot like Mindopali explained. It was an innocent down-time sitting on the toilet, I felt my pulse, pressed on it, nothing, tried a few millimeters above and below and suddenly my vision started to blackout starting at the bottom. I was thrilled. Also it's important how your head is positioned. If you're looking down the arteries tend to retreat to unreachable depths but if you tilt your head slightly back they are exposed.

Two days ago I was casually experimenting with the placement of this device. I was standing before a mirror, placed two empty socks under the rods to ease the friction on the skin then tightened the rods with a few rotations. It wasn't even uncomfortable, just the feeling of slight pressure. Nothing happened for 5-10 seconds, then I remembered to tilt my head a little bit back. I'm not kidding, after 1 second my vision started to black out the same way like on the toilet. No light-headed feeling, just straight to blacking out.

Now I feel less suicidal knowing that I have control over my life. It's a pleasant feeling that I have a tested device in my backpack ready to use when shit hits the fan. Makes me want to endure this life with level head. It's sad that it takes this kind of measure.

This method can completely block the left and right carotid arteries, but the vertebral artery can still supply blood to the brain, so I don't think it can Cause coma.

 

[2bearcolossus]

It supplies 20% of blood to the brain (mainly hindbrain) along with the internal carotid artery (80%).

I think the numbers are on our side. Good point though.

Thank you Bear for posting this.

I have been doing some research.

One fear is that as I throttle about the mechanism gets loose and looses the sweet spots.

Second fear is that I pass out and don't die because some level of blood is still fed to my brain.

Stressed

Other than that this mechanism is a dream if it'll work thank you again
Bear I wasn't able to see anything when I downloaded the file. What might I be doing wrong? Sorry I'm not very tech savvy

 

[2bearcolossus]

Hi Lisa, I used M30x3.5 mm normal metric threads on the rods and the receiving nuts. They are supposed to be self-locking due to plastic-on-plastic friction, so they won't get loose when they are under axial pressure (and not under gravity without pressure while we're at it). There are fine threads too, with even less pitch, which makes friction greater but it's not feasible for the nature of 3D-printing. I recommend fine print settings though, at least 0.2 mm layer thickness to increase surface-to-surface contact.

I tried this device personally, screwed the rods in hard (missing the sweet spots on purpose) and during the slight discomfort the rods were static. I even tapped them and they were fixed in position. It requires at least as much force to unscrew them than to screw them in. There's just no way they unscrew on their own in this state.

Some level of blood flow will still be present in the brain. The carotid arteries only supply around 80% of the total blood volume but it's still enough to cause brain death eventually. Think of it this way: once you're passed out due to blood flow restriction and stay that way, brain death is just a matter of time. But that's not for you to experience since unconsciousness involves timelessness too.

On a personal note: breathing and swallowing is still possible while wearing this device but it becomes weird once the rods are too far in. Then again, once the sweet spots are pressed the rods don't have to go in so much further. I once slightly missed the sweet spots and I experienced breathlessness but no sign of light-headness or eyesight distortion. I'm not sure if because of the partial artery compression or the partially closed trachea but it wasn't painful, I just couldn't catch my breath. I suppose it's possible to pass out this way too, but we should prefer straight to blacking out and let SI do its job while we're uncoscious.

No fear. Have you tried the passing out game before? I did a few times many years ago and clearly remember my clueless face on the floor not knowing what the hell just happened. If I were not to come back I wouldn't know I passed out or whatever happened to my body. My last memory was always holding my breath as I stood up. This is like 95% of my reason to remain calm in these dark hours/days/weeks. I once read somewhere that the carotid arteries are the human equivalent of the self-destruct button on a bomb.

You didn't see anything in the .zip file? Like it's empty? There are no pictures in it, just 3D CAD models, 13 of them.

Hi bear, I was more concerned about the rods moving to a non-sweet spot than unscrewing themselves. Hopefully that will not happen. Yes when I open the file it said like 13 filed or something like that but there was nothing there. But hopefully if I show the picture of the device to a 3-D printer Company they'll be able to mimic it yes? I'm trying to think of what I would say it's for or should I buy my own 3-D printer?

Thank you So much for your help

Nowadays you can get a 3D printer from any online store, you name it and they are inexpensive. But it's not a plug-and-play machine, it needs lots of adjustments, tinkering, troubleshooting. I'm very picky when it comes to perfection so it's safe to say that it took ~1 year for me to be satisfied with the results.
You can make toy guns with it, real guns not so much. I've heard stories about it but I'm skeptical.

Sorry Lisa, I misunderstood you earlier. I just tested the device for rod displacement and there's none. Once they are biting my skin through a layer of sock (or any soft cloth material) they won't move around. There are STL-files in there (6 of them) which are directly used in 3D printer softwares to slice the part into layers. No need to mimic anything. Service providers know what to look for. You probably don't want to show an image of the assembled device to anyone, it just asks for trouble.
But before all of this you need to tailor the device for your neck. I can't help you with this with good conscious and per rules of this forum, though. For experimentation the raw parts in the .zip should be good enough. I did 4 prints before I arrived to the one shown in the pictures.
I don't recommend buying a 3D printer without some experience, it's just not worth it, see my previous reply why.
And the golden question what's it for? "Well, it's for my Hellboy cosplay!". It actually looks like one lol.

Ah good one thank you!

Ok but back to that then, I cannot open the files. I'm going to try again now

 

[2bearcolossus]

A few more images of the compression collar. I forgot to mention that 01_M/F + 02 + 03 should be glued together.




Important dimensions:



Neck cross-section:



The person with this neck cross-section should bring the rods a few millimeters together so they move directly towards the red-colored carotid arteries.
Now by looking at it the blue-colored jugular veins are compressed and the carotids just slightly. This setup will only give the person a nice headache.

If enough pressure is applied I think the vertebral arteries may be affected too but I'm not 100% sure about this. Just by looking at it they are in the way of the rods.

 

[ron_g]

Could the rods be made just a bit smaller in diameter so they more precisely hit the arteries while not touching the trachea as much? In this case you'll be more dependent on the correct level of the neck though.
I wonder if there's a risk you pass out but do not die. And maybe will be found and "saved" the next day.
How strong will torsion of the skin be just before you've sufficiently tightened the rods so it would be successful?
If you want to hit the vertebral arteries, too, you'll have to place the rods at the very bottom of the neck.

 

[2bearcolossus]

The rods could be smaller but I would keep them like this for the good of "lazy aiming". Now they are 30 mm in diameter, the next lower metric threads are M24 and M20. Anything smaller is comparable to the diameter of the carotid artery and we'd like to compress it in its full width.
As it is now the trachea is not in the way. At least not for me.

I think there's definitely risk if someone is found within an hour, but for days I don't know. Passing out on its own means dangerously low oxygen level in the brain. It depends on the contraction of the arteries how fast brain damage becomes irreversible. Should be fast enough like partial hanging.
To be sure I would just wander deep into a forest with some water and stay there. Worst case scenario: I hiked a little bit and refreshed by nature's smells and sounds. Best case scenario: dead.

The torsion is not noticeable at all. I always put a layer of sock under the rods to keep my skin torsion-free. I only feel the pressure inwards which is quite bearable. There's almost an instant feedback when the rods are in deep enough. The dizziness starts after seconds, than blurring, glittery blackness fading in at 10 seconds mark. This is where I abort all my experiments because I know from the choking game that blacking out is imminent. 3 out of 5 times I manage to reach this point.

Thanks for the update on the vertebral arteries, I didn't know there's a level difference. At the level of carotid splitting it's protected by some bones right?
