"i&#039;m 18 and i have been using tri-sprintec for a week now.  i love it so far. i have not experienced any nausea or any other stomach problems. my back hurt for the second day i was on it, it was not bad and went away the next day. i have been going to the gym everyday because i want to lose a few pounds and it&#039;s been harder then it usually would be. i haven&#039;t lost any weight, but i haven&#039;t gained any. my boobs have slightly grown. not very noticeable.  i would recommend it."
