"i&#039;ve been taking  phentermine for almost 5 days and i&#039;ve lost 7 lbs so far. i also take topiramate but that is for sleep apnea and my migraines. i&#039;ve been eating only good things and only drank water. i find it extremely hard to eat over 1000 calories because i get full so fast. i have had so hallucinations and blurry visions as well as stomach pains. but other than that it&#039;s been going great!"
