"age: 36 weight: 230 height: 5&#039;7&quot; mother of 4 kids, i started phentermine 37.5mg tabs on 4/17/14. i take half the 37.5mg tab 1/2 hour before breakfast and the other half 1/2 hour before lunch. by taking them this way, it helps curve my appetite for the whole day. i don&#039;t have a scale in my house, so i&#039;m not sure how much weight i lost; will find out at my follow up doctor&#039;s appointment in 2 weeks. but, i can say that i can tell i lost weight when i look in the mirror and by the way my clothes are fitting more loosely. the only side effects that i have gotten are dry mouth and headache when i don&#039;t drink enough water. i seemed to lose the most weight in week 1, i&#039;m sure that was water weight. i&#039;m eating low carb/high protein, but need to exercise more."
