SN is tricky- I had an easy time getting it but I didn't bother with an antiemetic. I got drunk, took a handful of sleeping pills, and put a tourniquet around my neck. When I started nodding off, I drank the N and tightened the strap. I passed out and woke up covered in vomit and bruises from deathrolling I guess lol. And I generally have a strong stomach.
If I was going to jump, I wouldn't be comfortable with only 4 stories.
I have a shotgun that I plan on using in a week or two and am comfortable with those odds. If I didn't have a gun, I'd probably make another tourniquet/night-night method. I'm not sure I could do a proper hanging.
If you were gonna go that route, all you'd need is a ratchet strap (~$10 from Walmart), maybe some duct tape, and either those mini beanbags folks use to play Cornhole or even wadded up socks could work. If youre able to get the placement just so, you wouldn't even need it too tight. You'll still be able to breathe and you'll just kinda drift off... When I was practicing it actually felt really nice. The idea is to cut off blood flow to your noggin but not airflow.
I'd be glad to talk more about it but I'd imagine there's a proper guide somewhere that'll do a much better job of explaining lol.
Whatever you decide I hope youre able to find peace <3
Hey and please dont think I'm trying to talk down to you but to be clear - jumping 4 stories is a bad idea.
You might get very lucky and hit your head hard enough but you are much, much more likely to just maim yourself.
