weight loss
"I am taking phentermine 37.5, usually taking a full pill, but sometimes only taking half because of the way it makes me feel especially at night.  I have a hard time sleeping and have my heart pounds.  Hoping these side effects will go away but it has been a little less than a month and I still experience them.  I have already lost 22 lbs and hoping to lose the rest in another 2 months because my doctor said I can only take it for 3 months...if I keep losing like I have the first month I will make it.  I just wish I wasn't experiencing these side effects because sometimes they are really hard to deal with."
