I'm another well controlled T2 by my own and by my GP's definitions. I've kept to low pre-diabetic levels for six years now, but I believe what triggered my diabetes in the first place is still lurking about so if in the unlikely event I were to ever start scoffing too many carbs again I'd also expect to see diabetic glucose levels again.... I still get my diabetic checkups but HbA1C less frequently than before.
