I had these last night at Exit.I took the first one at 2:30am and around an hour later started to stumble around like i was drunk! then i threw up! i started to see and hear things that weren't there! really fuckin' creepy after an hour i started to feel mainline again, whew!!!! the next day i tested one on my friends kit and it came up possitive for DXM pretty quickly. DO NOT BUY THESE!!!!!
