"i started taking belviq 9 days ago and am down 7 lbs! the weight flew off the first couple of days (probably water weight) but i haven&#039;t lost anything for the last three. i really attribute that to not eating well when i do eat the last few days but i am eating less and less often. gone are my desires to snack. i made a salad for dinner and will be taking more control of my diet again so hopefully i will see some more weight loss soon! the first night i was nauseous and a little dizzy but nothing too horrible. the next day all of my side effects were gone.  i still get a little dizzy or nauseous from time to time but nothing too terrible. the biggest side effect is dry mouth but that just forces me to drink more water."
