Yeah I do the same lol I use sprite due to the citric acid in it and just because it dissolves shit like pills quick too. Yeah the onset is true ^^^ like he said 30 mins and with a full 20 it's much stronger and hits faster like 15-20 mins. I was saving them so I was cutting them up into half or quarters, but a full was quicker, nice, and strong- lasted all day too [If anyone is to do this chew them up till they are legit mushy, really soft, slimy shit then swish around some sprite or coke in your mouth for like 5 mins then bam you get a IR perc 20 high; it also last all day- as in, if you took another or a IR opiate then you'll feel it much, much stronger and last much longer.]
