"phentermine has worked very well for me and my own personal situation. i was formerly anorexic/bulimic with a habit of severe calorie restriction, phentermine has worked amazingly.  my metabolism went into hibernation after 5 yrs of damage &amp; i gained 180lbs post rehab. by taking phentermine daily, i have the metabolism of a nomal 22 year old girl. i lost 30lbs/90 days initially. now i&#039;m losing 30lbs/month.  occasional moments of feeling weird/adrenaline rush is worth it."
