"i have been taking phentermine 37.5mg once a day for the past 37 days. my obgyn prescribed it for me to take for 90 days. so far i have lost 16.4 pounds. my highest weight was 222lbs which is a lot for my 5&#039; 3&quot; frame. my goal weight is to be at 140lbs. this has really helped jumped start my diet. i had little motivation to lose weight because i felt like it was so much! i couldn&#039;t believe how much i had put on through the years. i was constantly starting a diet and trying to eat right but not working out and getting frustrated from the results. i also have pcos and gained a lot of weight from taking zoloft for my anxiety. i am counting calories and working out and hopeful to see even more improvement with my remaining 53 days on the medicine."
