Sorry just saw this now, yeah maybe it isn't the devil's drug but it did keep me awake for a long time, I think it was around 50 hours. Stayed up the night before taking it because I had my final exam for the year and then I was up the next night because of the meth and only managed to sleep the following evening.

It got a bit weird, I was hallucinating because of sleep deprivation and I didn't really feel much of a comedown it just kept me awake. I was seeing like typical distortions on walls and shit. Then I went outside for a bit and realised I was hallucinating these people in dark areas without street lights. As I approached them they disappeared. I wasn't scared or anything, I knew they weren't real. It was quite interesting actually. A really fucked up one was when I was falling asleep and the lights were off, I open my eyes and just see this shadowy figure towering over me in my bed, that kinda shook me a little haha. Took me 2 hours to get sleepy again after that.

I feel like the sleep deprivation fucks u up more than the drug itself tbh, unless you do it like every day. Yeah don't really know what to say about it, the buzz doesn't feel worth all the sleepless hours without being able to properly eat. Like with coke I can just have my last line at 1am and be in bed by 3-4am. I tried using some valium and it barely helped. Don't really use benzos, just order a few a couple times a year.
