"i was prescribed phentermine for weight loss as i was about 70 lbs overweight.  i&#039;d been struggling for 18 yrs with depression and anxiety from a traumatic event and even though the doctors prescribed antidepressants and anti anxiety meds, i still felt lost and sometimes suicidal.  within about 20 minutes after taking my first phentermine pill, i felt absolutely &quot;normal&quot; again.  imagine 18 yrs of struggling, not being able to focus, falling behind at work and at home, losing track of my thoughts and not able to hold a decent conversation then a weight loss medication gave me back my life.  as for the weight loss, i changed my eating habits, stopped drinking soda and lost 18 lbs within three months."
