When I was 17 I got home from a concert and was handed an envelope full of acid. I mistakenly took 16 hits of acid. I had sex several times while in the mist of the craziest moments of my life. I really felt like I was going to break sometimes. Never did anything like that since, this was 20 some odd years ago. But it is something that I still can remember vividly. Truly amazing and different.
