I've had numerous binges in which i've ingested more drugs than I could count on one (two?) hands, but nothing tops the sheer stupidity of ingesting somewhere around 150, large, fresh psilocybin cubensis between three of us...
Harm reduction? Well, at least we roughly counted it first. Stuck 'em in a huge saucepan, slowly heated the tea, really tried to make the most out of it. In hindsight, there was probably no need to ingest 50 each. Especially for the first time on shrooms!
Done shrooms twice since then, I honestly don't think I'll ever be able to enjoy them, thanks to that harrowing experience. Just waaaaay too intense, like can't move, can't remember who I am sort of shit. Kinda fun, but just too much.
Nowhere near as intense, but actually enjoyable, was maybe 3-4 MDMA pills, 1/2 g of coke, plenty of alcohol and weed over the course of a night, then necking a couple of hits of liquid acid at around 6am. That I didn't actually know I'd necked. Damn water bottle. Still, I appreciated the humour in the joke, as did my other friend who got suckered by it.
