"i am on day two of 30mg phentermine. i can already tell it&#039;s working, i&#039;m less bloated, my sweets craving is gone and i&#039;m rarely hungry. i tend to have to make myself eat not because i&#039;m hungry but because my body tells me it&#039;s time. i was on this medication years ago and lost 30lbs in 3 months. the doctor i am seeing now has no limit as to how long i can or can&#039;t be on this medication. the first month is to be focusing on eating habits. i love it so far! can&#039;t wait to weigh in and see what it&#039;s doing."
