I have been a diabetic since 2005. I don t know for some reason, some of the medicines that I have gotten from the doctor I don t think its working. My sugar is still kind of high and my a1c doesn t want to go down. Is it maybe that I am too long on one medications. And sometimes I feel sad and the doctor says it maybe from some of the medicines. Should I go to a different doctor and start from the beginning as far as taking medicines?
