"i lost 70 lbs in 6 mos. on phentermine 37.5 . i had to have surgery and the surgeon required me to come off of it 3 weeks prior to the surgery and 3 weeks post surgery, then i had some complications following my surgery... i gained 23 lbs back which was very disappointing.  

i just picked up my new prescription today and can&#039;t wait to get started again!
the only side effect i had in the past was the first 3-4 nights i had trouble sleeping.after that no problem!but the main key is drink plenty of water !
it does really work and you are not hungry!"
