"i was on this drug for about 3 weeks. it did not curb my appetite. in fact, i was increasingly hungry and could not stop eating. i gained 10 pounds on it, which i&#039;m assuming is not how this drug is supposed to work. once i stopped, my appetite returned to normal; however, now i have 10 pounds to lose in addition to the 30 i initially wanted. i am sure i was a unique case, but i would caution that if you start gaining, stop the drug. i felt like i needed to stay on it because it was so expensive and i didn&#039;t want to waste my money. and, my doctor said to give it time. well, 10 pounds was enough time."
