Why don't you try plugging the pill. You will roll harder & it also seems to make people less pukey Plugging is the way to go..It can be a few reasons , you rolled on a full stomach.. That you shouldn't.. Rolling also on a empty stomach makes you roll harder It can be the pill was 2 strong for you..Why dont you take 1/2 of the pill next time when you roll and see how you feel Try popping 1/2 or a whole Tums if you start to feel nauseous also I know with some of my friends after they puke they roll harder ;0
