diph 

Short for Diphenhydramine (trade name Benadryl), an over-the-counter antihistamine and sedative.

Side effects are consistent with tropane glycoalkaloidal poisoning and death at high overdosage.

Yo man I popped 20 Diph's last night and I could have sworn my house was on fire.

Diphenhydramine

Diphenhydramine is a drug used as a sleep-aid. It is often used as a recreational drug that is cheap and effective.

I've used diphenhydramine as a recreational drug before. If you want to you need to find out what high dose is right for how much you weigh. When I used it my light moved around, when I looked at my wall there were hundreds of flys all over it and it sometimes looked like my walls were smoking. I could barley walk and I didn't really know what I was doing all that much.
