Phentermine
"I am 41 years old and have been taking phentermine as of September 2, 2008 to December 20, 2008. I have lost 35 pounds. It has been a huge blessing in my life. I went from a size 20 pants and 2x or 3x tops to a size 10 pants and from large to medium tops. It is awesome. It has been a great experience but be sure to see a doctor before taking this medication. The side effects I experienced were dry mouth (I chewed sugar-free gum all of the time and drank lots of water) and constipation. It seems to get better after being on the pill for awhile. Energy (treadmill 5 to 6 times a week and get this - I love it). I'm taking a three week break right now. I'll let you know how it goes. Good luck."
