Phentermine
"I just started taking phentermine yesterday 2/8/2011.  When I weighed myself yesterday morning the scale said 273.0 I took the pill and my appetite was completely gone. I ate a very small breakfast and had to force myself to eat anything for lunch.  When dinner came I wasn't hungry but I figured I should eat something.  I drank 9 bottles of water because my mouth was so dry.  I didn't have any issues sleeping and I didn't notice any change in my energy level. When I woke up this morning I headed straight to the scale and I'd already lost 3lbs. The scale said 270.8.  I'm very excited and super motivated to continue."
