Stokie,
I've never had any meds. On diagnosis my GP gave me the usual pessimistic "I'll have to put you on metformin at some point, and probably statins too, but lets see how you get on with diet and exercise for 3 months" mantra. Then he was so blown away by the change in the first 3 months he was questioning the diagnosis (although there's no doubt I'm diabetic, I had two HbA1C readings in the 50s).
At this point I consider my T2 pretty much beaten. I am confident that if I don't eat any major carbohydrates from now on, there's no reason my BG should rise out of the 30s. My next task is to get my blood pressure down and get off medication for that. The key to that is weight loss, so I am going to have to look at more exercise and calorie control. I lost 11 kg initially and my BP dropped significantly, I then put 5kg back on and it was back up to unsafe levels, so I know what I have to do. But at least, for me, diabetes is last year's problem.
