Whenever I do a shit load of coke I'll feel ok and then later when I try to sleep I notice that my heart is flying, i'm sweating, etc... Anyway, already paranoid from the coke and I started thinking what if I did too much.. Does any one here have any ideas on whether it's possible that you'll OD (or just get medically fucked up, whether it qualifies as an OD or not who cares) like 2 hrs after you did alot of shit. In other words, will it only occur in the process/immediately after doing too much or do you think it could happen later when you're laying down after a binge to sleep? The idea usually crosses my mind after it's been a real long nite (like 4 hrs) of blowing lines pretty consistently after a nite at the bar (so from like 2-6 of doing coke and then attempting to lay down at like 8- retarded I know). If this post makes no sense, I'll try to clarify.
