Phentermine
"I started phentermine 37.5mg in March 2011 and weighed in at 180. By the end of April I was down 20lbs to 160. It gave me energy and really suppressed my hunger, but I had horrible dry mouth, constipation, irritability, and had to force myself to eat. Since I stopped, I have gained 10 lbs back in 7 months and is entirely my fault. I have started it back up again because to me the side effects are worth the outcome. It loses it's potency after a couple of months, but still suppresses the hunger more than without it. As long as I am dedicated to the program, I should be able to take off the 10lbs I gained and then some within 2 months time. My realistic goal weight is 145 and is totally doable with healthy habits."
