Thats what i hate about buying E in clubs, you dont know how strong is the pill u get. My first time i took 2 at same time, and i got blasted the hell out, when they started wearing off jest a little, i was "smart" enough to flush some K down, and then i was just beautiful! It was a very disoriented experience. Now i take more than 2, and im fine. I dunno, first exp was only bad one i had, everything else was pretty good. I guess i was jes very nervous first time, and thats what screwed it up. But E is good, in a good amounts for good parties. Keep Eing! Peace
