"i&#039;ve never been thin, always overweight/obese. my appetite is voracious, and i have poor metabolism related to thyroid disease. within the last year, i have tried countless times to lose weight with no results. i&#039;ve been on belviq for 2 weeks. it took about 4-5 days before i noticed any change in my appetite and until that time, i did not lose any weight. however, since the medicine has built up in my system, my appetite and cravings are down and my self control is up. i have lost 8.6 lbs. in 10 days. i am working out as well and counting calories, which is much easier to do with the added self control. my only complaint is mild joint/back pain. i can still overeat if i make/allow myself, so you have to be dedicated to losing weight."
