Is exit bag painless?

[randomuser97]

I have severe dissociation. I been looking into painless suicide methods. Exit bag seems very painless but I heard a lot can go wrong. If you do it correctly is it peaceful?

 

[UserFromNowhere]

Assuming you do an exit bag correctly, it is no different than falling asleep. As the oxygen in your lungs gets replaced with the inert gas, your brain gradually begins to lose consciousness and shut down due to the lack of oxygen flowing through the blood.

I am also very curious about this method and more so, how to properly use this.

As I do know that professional physicians definitely use this method as the alternative to Nembutal/pentoparbitol in cases where they cannot use that med.

Yes. I was told (by someone who tested it a number of of times & failed with it once before he CTB'd with it) that it's euphoric. And there's a video on YouTube that shows a pig fall over after exposure to it, and then it goes back for more (showing how painless it is).
All the answers of how-to can be found between the magathread linked below & Dr. Nitche's PPH.

But yes, it is a very technique dependent method. If a single step is forgotten or done wrong, It won't work. Even if everything is done right, things can still happen that cause it to go wrong (though not that likely).

Take time to familiarize yourself with this site. Read the informationalstickied threads on the main page of this part of the site, the last one in particular. Between that and what's in the PPH, you can decide for yourself which methods seem peaceful (or peaceful enough) to you. The answer won't be the same for everyone.

[behindtheveil]

As a potential user of this method, I wholeheartedly agree with DeathSweetDeath that this method although quite peaceful. does require a fair amount of technique perfection.
But I do wish there was an easier and available method. Something as the legendary "Peaceful Pill" that was supposed to be under development but never happened.

I have severe dissociation. I been looking into painless suicide methods. Exit bag seems very painless but I heard a lot can go wrong. If you do it correctly is it peaceful?

What it seems like in theory and what it is like in reality, are two entirely different things indeed. None of the commentors here have actually done it themselves, they have just read about it on the internet. But that does not mean that they can be sure there is no risk.

Indeed, a lot can go wrong. Your question of "if it goes correctly is it peaceful", accidentally leaves this crucial part out: "if it doesn't go correctly, is it painful"?

The exit bag suffocates your head, lungs, bloodstream, your entire body is suffocated, unable to breathe, et cetera. Believe me, I've been on this forum for quite some time (about 600 posts), interacting with people and getting a sense of forum culture. People think reading a few internet posts actually makes them immune to pains from suicide.

People endlessly, ad nauseam, repeat "but if you do it right, it's peaceful". Any counterpoint, that elucidates "there is no actual way to completely eliminate botching or unavoidable pain", people repeat "but if you do it right, it's peaceful". "If you do it perfectly, there is no pain." Little do these people know, the world we live in is not perfect, and no amount of reassurance from forum members will ignore the laws of physics.

There is always risk. No matter how much people here reassure you that it is "peaceful" or "riskfree", the laws of physics and biology will continue to stand, and there will never be a guarantee of no pain or increased suffering resulting. No suicide contraption is "flawless"—this is basically a hacky DIY project; there is nothing stopping it from going wrong and inducing severe pain or disability.

No suicide method will ever provide a guarantee of "painless" death.

For more information, read my post here; it includes a poem relating to this subject at the very end, as well. I quote Albert Camus—a philosopher who has written on suicide extensively. I encourage you to read it if you can; it mentions things that are not mentioned enough on this fourm.

Every method sucks, dawg

So everyone talks about SN, it seems like the most liked method here cause it is painless, but the SI is still there and requires lots of preparation. I can't think of a single method that doesn't suck in a certain way... either painful, super scary or too much planning, or all of the above.

sanctioned-suicide.net

Here are some posts from other users in that very same thread as well.

i think you are confusing immediacy with painlessess. What you're describing is a preference for radical physical methods out of fear of chemical failure. But claiming these methods are painless based on your personal feelings or forum posts is just as subjective as what you are accusing me of.
We both know the mechanisms of neuroreceptors and hypoxia, but theory ends where reality begins. Your mechankcal methods aren't better they are just more violent. Choosing impact or asphyxiation is simply betting on perfect execution. If you knew how many people end up with irreversible neurological or physical disabilities after failing these radical attempt , you would understand that the risk is far more terrifying than a failure of chemical sedation. Chemistry seeks to shut down consciousness your methods seek to break the body. Just because it is quick and dry doesn't mean it's painless

No suicide method is "perfect", none gives a surefire "guarantee" that no new pain will be experienced—potentially horrifically—by yourself. No amount of reassurance changes reality: there is serious risk of serious pain. Forum members must not understate this unsavory truth. It is not "pro-life propaganda" to state basic fact: I'm telling you, this is just how it works. You can write a reply to this thread post if you have any questions.

I wish there to be some niceness and relaxation in your day, even amidst it all. Take care of yourself

Sure. No matter what we do, bad things can potentially happen to us. Trying to CTB is not risk-free, and living without trying to CTB is not risk-free either.

This will be my method even though I don't think it's peaceful, as I can't get PSH to work painlessly for me. I did two test runs (just scrunched the air out from the bag above my head, pulled it down, and filled it with Nitrogen) and I didn't think it was painless, but I think unconsciousness could be achieved quickly if the gas amount was high enough, and you hyperventilate and take deep breaths beforehand.

For context, I put the Nitrogen gas at 17 LPM with my Argon regulator (I don't know the Nitrogen equivalent) and I was hit with a wave of symptoms within 30–40 seconds that were in this order I think: ringing sound, feeling I needed to spit/puke, dizzy, disoriented, and feeling faint. It was similar to taking too much Cannabis edibles if you ever had that experience before. I think all the symptoms subsided quickly, except for the disorientation, which took about an hour to clear.

In my second test run, it felt more painful with 13 LPM running with Argon regulator, as I felt breathless, lightheaded, and my heart rate spiked.

I'm sure it wasn't placebo effect or the CO2 buildup that was causing these symptoms. It was the Nitrogen cause you wouldn't even get these symptoms if you scrunced the air out of the bag, pulled the bag down, and breathed in the bag without Nitrogen but just the CO2 buildup.

There are people who say this is a peaceful method, but I think they were using a low amount of Nitrogen, gradually fainted, and survived. Or, the people that say this is a peaceful method never actually tried this method and just claimed that it's peaceful based on how quick LOC is introduced. I wouldn't trust the opinions of the people in the latter category, as they're just using secondhand information and it's confirmation bias at best.

What seems to almost be universal is that convulsions would set in (something which I have to account for) after you LOC.

Here is a user who CTB-ed from N (he gave up on Nitrogen) from a few years back because he found the symptoms intolerable: https://sanctioned-suicide.net/threads/exit-bag-and-inert-gas-megathread.8393/page-58.

Another user who found the experience intolerable: https://sanctioned-suicide.net/search/2494193/?q=sadcryingbunny&o=relevance.

There are several more accounts, but the symptoms essentially track with the symptoms I had.

All in all, in my experience, this method isn't the new N. You're not going to get an 'anesthesia' death, but more like a 'fainting' death.

I'm currently researching on ways to get this highly hypoxic state as quickly as possible, so that LOC would occur quickly and I could bypass the nasty symptoms (I don't even know if I'll be in-and-out of consciousness), but it's up to fate I suppose. I'm going to go through with this method when all my CTB equipment arrives, I've written all my letters/documentation/instructions, and after wrapping up a couple more tests. I'm trying to make this method as foolproof as possible, but there are only a handful of things that I can control cause once I lose LOC, I won't be able to control anything.

Exit Bag Nitrogen Video Test

When oxygen displacement is done properly, fainting occurs quickly: View attachment 180060

 

[latetoctb]

I had 1 failed attempt and 5 tests in which once I fell unconscious for 25 minutes. in all the experiences, it was painless but uncomfortable. Though, this is probably due to my issue of still getting too much oxygen and not being able to pass out quick enough.

I was stuck at times for half an hour, breathing heavily and sweating while being in a confused daze, half way unconscious until realizing finally that its not working and taking the bag off. The time dilation is very real and even though I was able to solve math problems in my head, I was often unable to figure out how long it had been.

I went through an entire 40cf tank with all my testing/attempt and was unable to figure out how to properly achieve the correct flow/tightness around my neck.

Looking back, I figure it was mainly the tightness around my neck that was the issue. From everyone's wording, it was very hard for me to figure out how tight it actually needed to be.

In my last test, it was the tightest and that is when I fell unconscious for the 25 minutes and eventually woke up on the floor (was in a chair) with the bag still attached well enough and I woke up to the sound of the tank running out of gas. Though I very well could have fallen unconscious in my other tests/attempt and not known at all. The only reason I know for sure about the last test was because I set up a timer in front of me and I had no memory of laying on the floor.

I was trying to make an account on here at the time to ask questions but got denied by admins several times for some reason they didn't say.

Nonetheless, I never experienced any pain or even twitching.

The after affects can be brutal though if you survive. Mainly extreme exhaustion for a few hours afterwards.

My last test ended up giving me some extreme loss of circulation in my limbs, especially my arms that made them curl up into my chest uncontrollably. Unable to move my arms or legs for a couple hours with extreme loss of circulation and static feeling at its peak. This happened 6-7 hours after I removed the bag from my head and I was convinced at the time that I had done permanent damage to my brain and ended up in the ER only to realize I was fine and the symptoms passed completely after a few hours.

I guess I viewed the uncomfortable symptoms I had (similar to yours although not as severe) as painful. I had anesthesia before on two occassions and that to me was the most painless and quickest way to achieve unconsciousness.

Can I ask what chair were you using? Did you restrain yourself with your chair?

How were you in the time-dilation state for so long without going unconscious? Was it because the bag wasn't tight enough as you mentioned or your flow rate wasn't high enough?

Would you say this method is a dud? I'm in the process of researching in terms of what chair to use, whether the people that fell out of their chair had restraints, and how could some people bear through the symptoms at X flow rate?

 

[latetoctb]

I guess I viewed the uncomfortable symptoms I had (similar to yours although not as severe) as painful. I had anesthesia before on two occassions and that to me was the most painless and quickest way to achieve unconsciousness.

In hindsight, would you say that the failures were because of the tightness? Also, can I ask what chair were you using? Did you restrain yourself with your chair?

Yea the heavy breathing (almost gasping) and sweating is very uncomfortable, even noticeably through the confused state.

Yes I would say it was because of the tightness. Though it could easily be a few problems going on. The procedure seems pretty precise to pull of, especially if using a home made exit bag. Figuring where to place the hose and what angle and how to secure it is it's own set of problems to solve.

I did find that increasing the flow rate helped some as well. From 15 to close to 20Lpm. But this could easily just be because I was messing something else up and this was compensating. Like the bands not being tight enough around my neck. Not sure.

Maybe I'm just not as smart as I think I am and this method is more simple than I experienced. It seems others had no problem in using this method with success.

For my tests, I was in an office chair as I thought I would be able to notice the unconsciousness coming and be able to remove the bag fast enough. This was the case for my previous tests. But the last test, I didn't even see it coming apparently. I don't have any memory of starting to fade. It was the first time I've ever passed out in my life and was very weird/interesting.

For my real attempt, I was in a recliner and had straps going across my chest and arms. Though I think the only reason I moved in my last test was because I wasn't stable sitting in the office chair. Like my body couldn't fully relax without falling and so I assume that's why I moved onto the floor somehow while unconscious. I didn't have any bruises or aches so I assume I didn't just fall or slide. The chair was positioned to suggest that I did it with some elegance but I'm not sure. It would have been interesting to video record.

Sorry to hear about the awful experiences you had. Thanks for sharing – it was informative.

I don't think you should attribute the fault to yourself. Let's face it. It's not a good method. An ideal method would be lights out immediately and no in between symptoms or aftereffects. It would also be easy to execute. I'm wondering now that maybe there are cases where we think the people that CTB-ed didn't and ended up surviving, but in debilitating conditions.

It seems like it's official, you need to have a reclining chair (e.g. zero gravity chair), restrain yourself, and have as much Nitrogen in as quickly as possible.

Haha yea thanks to all the great people against suicide, that's no longer an option for the subjects of this hell XD

I've also thought about this but I dismiss it as I think it's too paranoid lol though, hypoxia can give you permanent severe damage so it has to have happened at least some.

With learning about the newer method of using the EEB Hood, this seems much more reliable if you can afford the extra cost. I cannot unfortunately as my tank was also seized after my hospitalization and have now moved onto the SN method.

I don't know if I'll get the EEBD hood cause I don't have much time to build the setup. In a perfect world, I'd like to get my hands on the equipment that some folks that successfully CTB-ed from this method used, but that's not happening. Vizzy failed one of his Nitrogen attempts too, although he did it when he was in a sleeping position. I'm guessing this method doesn't work when one is lying down. It only works when you're sitting in something like a recliner.

Hmm I'm not sure what all would change when lying down. The pressure on the bag from the surface you're laying on shouldn't be any different from a recliner. I've heard others say not to do it while laying down but nothing comes to mind as to why exactly.

I wish you the best of luck with this method, I hope my information helped you plan better. Feel free to PM me if you have any other questions come up!

I've seen this before. I know they died, but it's ineffective. How would you explain Vizzy surviving the first attempt and @latetoctb surviving from the test run? Why is not recommended that people not do it lying down then? Why go through all the hassle of getting the right equipment then? If it was a walk in the park, then we can all just get the cylinders and fill it up and be on our merry way.

I assume I did not CTB that day because I ran out of gas and/or the seal around my neck had changed when i moved to the floor.

Though I was unconscious for around 20 minutes, I didn't have any permanent damage which is very surprising.

 

[Intoxicated]

I know they died, but it's ineffective.

If they died, it was effective for them. This position could be less efficient in case of using helium, since its low density can imply better displacement of air downwards than in other directions. This doesn't apply to nitrogen and argon (although nitrogen is slightly less dense than normal or exhaled air as long as their temperatures are equal, the difference in the real temperatures under the conditions implied by the given method can easily make relatively cold nitrogen coming from the cylinder slightly more dense than exhaled air and air entered the bag from outside).

How would you explain Vizzy surviving the first attempt

Difficult to say without having the full picture.

Why is not recommended that people not do it lying down then?

The argumentation in the megathread assumes a higher risk of displacing the bag in this position. It sounds reasonable.
