For Weight Loss Prescribed Belviq about three months ago- April 2016, 10 mg twice a day. Went to the doctor two months later and had lost 15 lbs from 266 to 251. Again, I went two weeks later and I was down to 246. Had some side effects such as fatigued, dry mouth but just drink more water. Does a great job of curbing my appetite-making me feel full on less food. Also seemed to change my taste buds. Doesn't at all agree with Alcohol. This is the first drug that has helped me lose weight. This is important since I am on estrogen blockers due to Breast Cancer and had a hard time losing weight. Will continue on this medicine.
