I started Belviq in May 2016. It is now mid August. I have lost 24 pounds in 12 weeks but I feel like the drug is no longer working. I've been lucky that there have been no side effects. At first it truly suppressed my appetite. I was full after eating half of what I used to eat. However now my appetite has returned. I feel my weight loss is attributable to exercise and healthier eating choices. I need to lose 100 pounds so I'm not even close to my goal.
