I recently went to mexico on vacation, needless to say i ate carbs for 2 weeks, gained 8 pounds it took me like 4 days to loose it this stuff is amazing, and i have no side effects from it, when i work out i have to watch it because my boyfriend told me if i loose one more pound he won't speak to me. and i really loose fast, now is just for maintainance, but is good to know i have it, for those hard days.
