I have been on Belviq for 9 days and have had no weight loss what so ever. I've stayed the same. I'm a 25 yo female and weight 260. I ride the stationary bike or walk at least 30 minutes 5 times a week as well as weights 2 times a week. I have noticed a decrease in my appetite-I no longer go up for seconds. Is there anyone else out there with similar experience? Does it maybe take a couple of weeks to really kick in and really work for some people? I'm very frustrated. Any advice or sharing or similar stories would be great. Thanks guys!
