Benadryl is so scary. never tried dxm, but i would not suggest mixing. Even a good trip on beny is scary. I see stuff explode, then implode and move in an unnatrual manner. I was talking to my girl for like an hour, went to hang up the phone and realized i never even had it. and its too easy to get caught. i cant walk right. and my voice sounds weak. i did it yesterday and didnt get any sleep.
