"i gained about 35 pounds from implanon and couldn&#039;t seem to lose the weight after i got it removed. i tried for almost a year with absolutely no results until my doctor prescribed me phentermine. this is the first time in over a year in seeing the number on the scale go down!!! i&#039;m still on my first week, so i&#039;ll post again once i&#039;m done with this medication. i highly recommend and the only downfall is sleeplessness at night but i just take some supplements to help with that."
