weight loss
"I am a 5'4" 42 year old woman who was diagnosed with hypothyroidism in 2000 and went from 130 lbs to 164 lbs overnight.  I've been trying to lose the weight with a nutritionist and through exercise.  I even ran and trained for a 1/2 marathon in 2006 and 2007.  The lowest I could ever get was 150 lbs and if I quit running long distances, the weight comes back.  I started taking phentermine on July 2 and have lost about 10 pounds. My only side effects are extreme thirst and occasional anxiousness."
