"i started out on 3-5-15 doctor prescribed the med but i didnt fill the script for another week. i started cutting my portions and quit drinking pop and eating anything that has a large amount of sugar cut out most of the bread and potato&#039;s. i then started taking belviq had no side effects other than loose bowels for a day or so. weighed in after 12 days &quot;5 on belviq&quot; and had lost 15 lbs. i have since lost anywhere from 2.5 to 7.5 lbs a week. weighed in monday 4-20-15 and have lost a total of 41.6 lbs. close to a pound a day. im not sure how much the meds have helped but i occasionally forget to take one in the evening and usually will notice i have more cravings 2 days later. over all i am happy with the meds. i feel much better now."
