I have been on Phentermine for a month now. I have not lost even 1lb. I have high blood pressure, diabeties 2, hypo thyroid, all of this showed up in one year with 50 extra lbs of weight. My new doctor prescribed me Phentermine 37.5 one time a day, removed me from the diabeties medicine and 1 of the blood pressure medicines. He says I will loose weight and everyone deserves a chance. I am 40 years old and I work and go to school full time. I take care of 5 children ages 11-23. I am on my feet all day, and I walk on a regular base. I just don't understand why I'm hungry still on this medicine. I also do not eat big meals but small meals all day, water not soda's and I eat many fruits. Is it that I will be like this or worse the rest of my life regardless?
