About the N2O, I know

. I've been reading your posts about the method & I'm intrigued. I know you've put a lot of research into it (as well as the collar), If it were more tested I'd be tempted to go with that myself.
What exactly is the feeling that occurs when you are suffocating? Both the sensation and what goes on in your head during those "last moments"?
Did your self preservation instinct kick in or did it just not work?
I just read your post on N2O, I am incredibly surprised I have not heard more about it in this context.
Dave - from what I can gather, several people on this site have spoken of attempting to ctb with a plastic bag in their past. Almost universally, they say you get to a point where you become extremely frantic - I heard one user say that it felt like millions of ants were crawling under his skin, urging him to move - so finally they just rip the bag off their head. Air hunger, while not painful per se, is an extremely difficult thing to deal with, it seems. While I believe that people over exaggerate "SI" as if it's some automatic force that takes control of your body, I believe that things like drowning and asphyxiation from lethal CO2 concentration, which is what is happening when using the plastic bag, are probably the best demonstrations of SI. With other methods, I believe SI only gets in the way when someone is not 100% sure they want to ctb. Which is a good thing, for sure. As we all know, this is the single biggest decision most of us will make and it should never be taken lightly or not looked at as an absolute last resort. I believe if someone is absolutely certain they want to ctb, SI will not be a problem.
There are quite a few case reports on the Internet of both accidental (mostly) and deliberate attempts to ctb with N2O. I don't know how true this is, but I had read that nitrous was the preferred method of ctb for dentists, who obviously have the stuff in their offices.
I would not be surprised if, like helium, people start using it more to ctb and it either gets banned completely, or mixed with oxygen or something.
I did see a stat the other day that mentioned deaths from nitrous asphyxiation were up 500% just within the last few years - most of these, as stated, were accidental. Given N2O attenuates the feeling of shortness of breath (given you presumably aren't breathing any oxygen), people don't even realize it and just lose consciousness, eventually dying.
