"i started taking phentermine 30mg in september 2011 am now taking phentermine 37.5 mg since the end of october 2011. i don&#039;t take it on the weekend and i&#039;m almost at the end of my three month &quot;try and see period&quot;. i like the fact that i have more energy with the phentermine but i can&#039;t tell a huge difference on the weekend. when i don&#039;t take it i just try to make myself get up and move and not just sit the whole weekend and eat (this is what got me to the point i was). i am 5ft 8 and weighed 226 when i started phentermine at the end of september 2011. today is january 2 2012 and i weigh 203lbs but i don&#039;t just rely on the pill. i have started going to a zumba dance class twice a week, for an hour each class and i also bought a kinect and not eat as much junk food as before."
