Phentermine
"I am a female  with hypothyroidism, post menopause and over 50.  I was at the heaviest in my life gaining over 60 lbs after being diagnosed with my thyroid disorder. I finally found a Dr. who would put me on Phentermine. I have been on it for a week short of 90 days and I've lost 32 lbs. There's nothing that in my 7 yrs fighting this hypothyroidism that allowed me to lose even 10 lbs. Not even cutting my daily caloric intake to less than 1200 calories a day. Which my Dr. wasn't at all happy about since she says 1400-1600 is the very least someone should eat.  I am so very happy with the results. I wish of course I could have lost the entire 60lbs I gained when I got the slow thyroid issue. But I am nevertheless very pleased."
