I was diagnosed with Type 2 diabetes in 1998, though subsequent events suggest that I really have a form of insulin sensitive genetic diabetes (probably MODY.) I used a very low carb diet for years, then switched fast acting insulin at meals, then repaglinide (which is extremely effective for some forms of MODY). My blood sugars improved very suddenly a few years ago after taking CoQ10, for reasons no one quite understands, and I currently am just watching my carbs and taking metformin.
