Nope Nope Nope, couldn't do it! LOL No way in hell. Peaceful loss of consciousness is a bunch of bills with some liquid courage.I've had the opposite experience. Lack of oxygen would be a peaceful death. You just lose consciousness, like falling into an abrupt deep sleep. When you want to die, you're not scared. You're scared only when you want to live.
You are right though, if you are serious about dying, you probably don't have any fear.
