"i was prescribed adipex by my doctor 9/18/17 and so far so good. i do not own a scale so i am waiting on my monthly doctor visit so that he may monitor my weight loss. the first day i felt like i could run a marathon and i did not at a thing that day, but drank a lot of water. the next couple days to a week it evened out a little better not as hyper, but enough energy to function. i am taking the 37.5 i take a a half of a pill in the morning and a half in the afternoon as prescribed by my doctor. your doc may prescribe differently, but this does make the effects of the drug easier to handle. i started off at 250lbs ( i hate to admit) and being only 5&#039;3 i feel terrible about my weight. i want to be at 130 when finished"
