"hello everyone. i&#039;m a 30 yr old female. my starting weight is 396. i went to the dr looking for help. he gave me a choice between 2 meds ( phentermine and contrave). i choose phentermine. i started taking the pill on may 4, 2017. he suggested i start taking half a pill just in case it would speed up my heart rate. after 3 weeks of taking half of pill i started taking the whole pill. i&#039;ve been on the pill for a month and i have the most energy. the scale says i&#039;m down 19lbs!!! my clothes pretty much fit the same but i can feel i difference in my walk. my back ache is no more. i can stand and have conversations at work without looking for a chair or leaning against something. i have changed the way i eat also. i cut out fast food."
