"i have been taking belviq for 7 days. i&#039;ve lost 6lbs. i feel hungry at random times but nothing ever looks good. portions are really reduced. i had dry mouth first two days but no other side effects. i want to drink water all the time now and can&#039;t seem to finish an alcoholic drink. i have polycystic ovarian syndrome which makes weight loss ridiculously hard, this medication is a fantastic motivator."
