I have to agree with RedRainDrop. Benadryl trips are pretty scary, but I'm sure you're going to do it whether we say they suck or not, so, take a look at the dosages here: http://www.erowid.org/pharms/diphenh...ine_dose.shtml

I took 18 25mg pills my first time and I just remember some scary visuals and some even scarier sounds like people talking to me that weren't there and shit.

I've tripped off it 2 times now and I don't plan on doing it again so give it a try but don't think it's the next DXM or shrooms.
