As an experienced drug professional, the not sleeping psychosis is 100% accurate. Not sleeping only 1 day is manageable, after that- shit gets weird and difficult real quick.
As someone who can't even do weed without having anxiety attacks, i'm oddly fascinated by people like these who can go deep into the hard stuff for a long time, and somehow make it out alive. It seems like fun...until it isn't.
My drug talk from my mother, when I was about 14, went like this " Life is hard. It's normal to be depressed. As long as u can still handle your business, do whatever gets you through the day" So no matter what I'd been doing all night/day, I still always went to work. Because it wasn't a problem as long as I didn't miss work. Lol. Ppl I partied with were always amazed. But it helped circumvent the guilt
