"i started contrave on june 19th, 2015. once i got over the side effects and dosage increase, i had no cravings for sweets or snacks at all. i lost weight very quickly. in the past month, i have noticed that although i eat less as a whole, i do find myself taking some sweets and snacking a little. i have lost 20 lbs, however last month, i did not lose any weight. anyone else feel like you sort of build up a tolerance to the drug, and it becomes less effective? any suggestions for me?"
