"everyone&#039;s different and some folks won&#039;t need the 20 mg a day. this medicine makes you feel like you never had an issue with cravings. they are gone, 100%,. after a while you forget what it was to have cravings and you may think the medicine isn&#039;t really doing anything, but try skipping it for a day or two and it will all come back to you! i still want to eat, just not bad stuff or big portions. i get hungry, but never so much so that i can&#039;t make good choices. that&#039;s the beauty of it. i think it will have to be made available for maintenance, maybe a lower dose, not sure. i wish more doctors knew about it. so many people are missing out on something that could really help them."
