MDMA.
Don't always get bad comedowns, sometimes i get an awsome afterglow, but when I do crash hard, it's fucking terrible. Hours or days totally fucked up and depressed, feel like shit, hate my life and everything about it, can't deal with people, snap at the smallest thing. Just want to curl up in a ball and close my eyes and not wake up until it's gone.
And that's why I've decided to cut back on my E useage.
I honestly don't get that bad a crash from meth. I feel kinda tired/sketchy/paranoid, and want more, and just generally irritable and strung out, but it's not the 'omg this is so horrible JUST MAKE IT STOP' of a bad MDMA crash.
