"i&#039;m 21. my starting weight was 165. for my height, which is 5&#039;1, i&#039;m considered obese. i have been taking phentermine since 04/29/2016, which is 4 days. i have already lost 5 pounds!! i eat small portions, i started drinking nothing but water, and i started walking/running 2-3 times a day. i walk/run first thing in the morning after i eat, again when my daughter takes her 3 hour nap, and once later on in the afternoon when it&#039;s cooler outside and i can take my daughter in her stroller. so far i&#039;m beyond excited because i may (or may not) reach my goal weight in only one month, or maybe two months. my goal weight is 125-130."
