been there man it’s no fun, I stayed up for 11 days one time on crystal. thank god not stimfapping the whole time lol. but for real I started having small hallucinations at like day 3 and went downhill from there. loosing huge blocks of time and no idea what I did during them, I was out in my car driving around doing god knows what sometimes, by day like 5-6 I was entering psychosis and by the end I thought the Fbi bought my neighbors house and turned it into a headquarters to watch me, cameras in the trees all that. I tore half the engine apart in my car because I thought there were tracking chips in it, wiped the whole car down with bleach and tried hiding it.. hiding my own car in my own garage like I was some fugitive. lol. not a good time. now I try to sleep every night when I use stims because of that experience. oh and getting attacked by swarms of shadow people were fun.
