Started taking Bydureon then the insurance would not civetover cost so the PDA put me on Byetta which was completely awful. She told me it was just like bydureon except I took 2 shots a day instead of one a week. I stopped it after 2 shots and tried diet and exercise. That worked so well. Numbers were never higher than 130. After about 2 months my numbers went as high as 250. Now I'm taking metformin and my levels are not as good as they should be. Any ideas why this is happening?
