I tried before I accepted meds and it did not make a difference for me. I actually kept gaining weight at abnormal quantities. I have had a long run in the past 1 1/2 years. I have had horrible reactions to every single med the doctor has prescribed. I have had fibro for 12 years now and I absolutely hate taking meds because most of the times they make me feel more sick than better. Metformin put me in the hospital. From there on have been reaction after reaction to everything. 2 weeks ago we decided to try Victoza an I was feeling great, besides some cramping on my arms and legs. I started with .6 and when I went to 1.2 my muscles started to get extreme pain. 3 days ago I couldn't walk without limping because of the amount of pain. My doctor says is not a reaction, however, I stopped 2 days ago and the pain is slowly going away. If the pain goes away completely I will consider another doctor simply because my reaction was dismissed as something else.
I don't know how out of control your diabetes is, but I have not met one single person who is full blown diabetic who has been able to manage it completely with diet and exercise.
