I just tried some benedryl last night. I had a HORRIBLE time with it. I'm 5'9 about 195 and a real lightweight.. and took 5 pills to start. within a half hour I was feeling anything and took another three totalling 8 pills. After an hour and half of taking the first five I felt tired and stoned. Nothing major. I figured fuck this.. I'm just going to go to sleep because I'm not feeling anything. I could not fall asleep though despite being very tired. After two and half hours.. everything increase in that I was feeling heavily stoned. Everything just seemed surreal. I kept trying to fall asleep but i couldn't breath right. My chest tightened, and even though I was breathing, I felt like I wasn't. That's when things got really bad. I started to panic which only made the whole breathing thing worse, and I wanted to come down off this "trip" ( and I use the term lightly) but just could not. The last time I looked at the clock was around 4..4:30 am. I must have fallen asleep a little after that. Waking up today was hell. I slept till about 4pm. When I got up I felt really sluggish and "out of it". I forced myself to get some water and to go out and smoke a ciggarette. I just couldn't shake the feeling for the rest of the evening though. Everytime I tried to eat.. I felt nausceas. It's now 12:15 about 22 hours since I took the pills and I still feel kind of out of it. Can't focus eyes, having trouble typing conherent senteces..etc. I would not recommend it. I've read alot of people having awesome trips off of this stuff but this was just not one of them. Stick to weed/acid/shrooms and such.
