"i started taking phentermine 37.5 mg every morning about a month ago. i&#039;ve always eaten pretty healthy, but after being laid up for 3 months after surgery, i gained 14 lbs and couldn&#039;t shake it off. in the first week, i lost 6 lbs. starting the second week, i gained 4 back. nowhere in the prescription information did it tell me that alcohol has an opposite effect on the medicine. i stopped drinking, and am steadily losing 2-4 lbs per week. only losing 10 lbs in the first month is discouraging compared to some of the reviews i&#039;ve read, but i only had about 20 lbs to lose to start with. my appetite is under much better control now, i can&#039;t eat near the quantity of food that i used to. thanksgiving dinner yesterday was a true test, and i passed!"
