Ok, with Diphenhydramine 225mg ain't really enough to make you trip, and I don't have much experience with Dramamine. Though when I did trip on Diphehydramine I really couldn't hardly move, but that seems to be a staple of my drug-usage: not wanting to move (except for some shit). So good luck walking around while on Diphenhydramine. I fell asleep before I came down so.... can't help you there.
