Around about 26 hours ago I had about 3-4 grams of Cocaine, spread out over a period of 4 or 5 hours. I'm still experiencing lots of twitches and I keep jumping and getting scared at things like doors closing, even when I closed the door myself. I am also experiencing hallucinations like the classic cocaine bugs under my skin, bats and other flying things flying around my room in the dark and I've seen several cars drive by on busy fast roads backwards (and no, they definitely weren't reversing). I've taken cocaine a large handful of times and never experienced anything like this, I actually dislike the fact that is doesn't last very long at all. I haven't been able to stop touching my nose all day and I keep sniffing, I've experience this sniffing thing before but no where near as much as I'm doing it at the moment. I'm also experiencing mild paranoia and the inability to sleep.
Any help would be very much appreciated, thank you.
