I have been a type 2 diabetic for 20 years. My A1C has been in the 6 range for about 16 years with diet, exercise, metformin and actos. 4 years ago my A1C went up to 8. I lost WT and my meds were changed to Metformin and Glipizide. A1C went back to 6 range. 2 years ago A1C was 7. Lost WT, increased exercise, low carb diet. I was started on Lantus. For the last two years I have lost WT, but my A1C continues to go up 7.1, 7.3, 7.7. Are any of the newer glucose control medications worth a try?
