I tied a belt around my door knob, while on xanax and vodka, this wasn't the first time I tried partial suspension this way, but this time I felt serious about it, so I took all of the xanax I had left, I think it was only like 12mg and drank a sizable amount of vodka in the hopes that I can force myself to pass out, because my previous attempts sober were just too hard to pull off without bailing out and I still didn't have a good grasp on where my cortical was, until that night, I finally managed to apply the pressure into the perfect spot
I found I just started to feel a prickling feeling on my face as blood flow was no longer going to my face, then my vision started to blacken (sorta like when you walk into a dark room after being in the sun) enough where I couldn't keep my eyes open, thanks to the xanax and the fact I'd been practicing for a week ahead of time I wasn't panicking too bad as I was losing consciousness, I was actually kind of excited! Then I just remember opening my eyes again, with the belt loose around my throat and a decent head ache, I'd kinda lost the will to try again at that point so I just went to bed.
It really only took like 45 seconds I think to fully lose consciousness, though I'm not fully sure whether I passed out because of the xanax or if I was doing the partial suspension right. The main thing that will be a source of discomfort before you succumb would be the feeling that your head will explode, and SI ofc, because SI is a bitch
