Phentermine
"I started taking phentermine on October 18, 2008. At that time, I weighed in at 263 lbs. I'm 5'10 so I carry weight very well. As of my weigh in yesterday (April 30, 2009) I've lost 41 lbs. The only side effect that I've had to deal with is insomnia; but over time, that has gotten easier to deal with. I'd recommend this medication; however, I would also stress that the weight you put on wasn't put on overnight and therefore, won't come off overnight. Slow and steady wins the race."
