"i&#039;ve been on phentermine 30mg for almost seven weeks now.  my start day was 2/1/14 and i weighed 215lbs. my last weigh in was 3/15/14 (6 week mark) and i weighed 194lbs. that&#039;s 21 lbs in 6 weeks! i just weighed in this morning and i&#039;m down to 191.5lbs. hope to meet my goal of 190lbs by saturday. i eat low carb (not induction low) and exercise 3-4 days a week. next week i&#039;ll be starting my day with morning cardio sessions. no complaints as of now. i love this."
