Been fighting it for 3yrs.
A lot will depend on wether your diabetes is hereditary or not, mine is and my A1c was at 7.5. Changed diet drastically and exercised, lost 25#, no change. 3 different meds later and it has gotten down to 6.1. I will probably not ever get off some sort of meds.
Diabetics is not curable only controllable. Lifestyle change is the hardest part!
