I got a bottle of this when it first came out and didn't use it all, well I found the bottle with just a few left and I couldn't remember why I never finished them, so I took 3 and went to work, like 4 hours later I had a stomach ach and whent to drop a bomb, a little bit later my ass started burning, by the time I got home my ass was burning so bad I jumped right in the shower and scrubed it for like 15 min. and had to put baby powder on it to sooth the pain........oh yeah, thats why I stoped taking it the first time....
