A few months ago I took 3 hits of acid. I ended up playing Jungle Book on a Sega Genesis and twirling glowsticks for about 8 hours. Then the next day I walked 2 miled from one friend's house to another's. In the middle of my walk I started tripping again and saw little Bambi-type animals run across the street. Anyway, I didn't sleep for three days.
It wasn't really a bad trip; I just wanted it to be over, and afterwards, I felt worn to hell.
