"at first i was on citalpram and i kept having the dosage bumped up. then i switched to pristiq which came along with a few mild symptoms including nausea. then it went away, and i noticed a change in my anxiety levels. i became confortable in my school environment for a change. after being on it almost 6 months, i am beginning to think it has quit working, and is giving me some constipation and belly pain. but who knows, that could just be something else. i recommend at least trying the drug if you need it."
