"i have been on belviq for 21 days and have lost 20lbs. i was fortunate not to experience any side effects. my constant urge to eat was subsided almost immediately. i find that i have to make myself eat most days. i have lost 14 inches total so far and can&#039;t wait to see how much more i lose. this medicine has been a blessing for me. go to the dr this week for my first checkup and am actually looking forward to getting on the scale!"
