"i started phentermine 37.5 on may 29, 2015 (a month now). i was at 211 (my biggest i&#039;ve ever been). i already eat pretty healthy and exercise everyday for about 2 hours but i was not losing any weight. i had a friend that was on it and lost about 50 pounds so i thought i would give it a go. i got a small headache like one or two times, i still sleep really well. i went from 2011 to currently 196, a total of 15 pounds in one month. i&#039;m hoping to lose about 50 pounds so i could get at a good weight. i bike ride everyday and run but since i&#039;m starting my second month of dosage i am going to work on ab workouts and lifting so i can try to get toned. i&#039;ll make an update soon!"
