Ok from my research: If you are anywhere between 120-145 pounds in weight, a trip strong enough to make you hallucinate like a lunatic is anywhere between 750mgs-900mgs.

From 145-160 you will need about 1000-1200mgs, I wouldn't suggest taking more (anti histamine has known to cause bleeding eyes in high dosages. And two boxes seems rather high.)

My friend finally got the right stuff yesterday. He took 24 hard tablets=600mgs. He didn't even trip for more than 3 hours, only saw a cat and a spider, and laid down the entire time. He had more fun snorting acetamenophen. So I suggested to up the dosage to double (he's a tough ass kid and will take like 5 hits of acid when he's never done it and still will have a good trip) we'll see how that goes. It's funny, taking benadryl kinda prepared me for acid, don't know how but I wasn't scared at all. Benadryl trips are scary for me, but a mad good time if you want to be a delerious fuck face. :P
CannabisGeorge Reviewed by CannabisGeorge on . URGENT FRIEND ON BENADRYL Ok, I am myself a pretty experienced benadryl user, but my drug newbie friend is not. He said he snorted 10 benadryl half an hour ago, and I talked to him on the phone, his strip had started. He kept talking to nobody and said pamela anderson was at his house, he even "gave me to talk to her". I dont know about snorting this shit, but it sounds like hes fucking tripped out as FUCK. he asked me who i was about 7 times, and at the end i told him to go online so i could talk to him, and its been Rating: 5
