That is helpful to know about the SI even with pills and alcohol because that was my plan. Get myself ready and then take enough to black out and fall off the chair or stool or whatever. I've always worried that the pain and shock would wake me up even with blacking out. That is terrifying. I wish there was a simple attempt. Even seeing so many people survive gun shots is like... damn. I've always wondered how people I know managed to do it.
It's surprising how much pain (or preconceived notions of pain) one can endure when they've reached the point of no return. It's almost like the mind just goes blank and your body is a machine working towards one goal. The pain is there, sure, but you just don't fucking care anymore, because soon you won't ever have to feel pain again.
At least that's how it felt for me several years ago. Unfortunately- and much to my humiliation- I chose a wildly unreliable method. I did all the grueling work of severing my radial arteries and didn't even die. For the love of god, it takes way too long to bleed out..
But even then, I never once had any survival instinct. It's just that I had been bleeding in that damn tub for hours, and I could hear the other person in the house waking up, so I had to abort my mission and clean up the bloody mess before they found me and had me committed.
I wish I'd realized then that I could have found information for more reliable methods online. I had no clue.
I now have SN and some ropes handy for the next time I reach my limit. I don't think I'll go with SN, because I happen to really hate being sick to my stomach (as this is an almost-daily hell I already experience.)
I will likely go out by hanging. The carotid arteries are the key to making hanging more peaceful; but I know from experience that I won't care much about peacefulness or pain when I reach the point of actually carrying out my next attempt. (Side note: It's not that I'm some kind of 'badass' with a high pain tolerance or anything. I'm really a huge wimp, seriously. But when I'm suicidal, I seem to swell internally with a lethal mix of despair + rage, and every ounce of that mental poison gets directed towards myself.)
