"i have been on belviq for 1 month and love it..the first week was hard, because i was put of it, had muscle aches, and just didn&#039;t feel right..after week 2 i felt great and now i have lost 20 lbs, which probably isn&#039;t healthy, but i had to force myself to eat..i noticed when i am hungry i am going to healthy foods rather than junk."
