It really depends what your HbA1c goals were. I was not satisfied with 6.0, I would rather be closer to normal in the 5.0 range. So I stay on Metformin, the maximum dose to achieve that. I seem to be very insulin resistant and the metformin helps me become more sensitive to my own insulin, which for me is a good thing. I don't believe diabetes can be reversed, but it can be managed. I am already eating pretty low carb and if I went off metformin I doubt I could eat anything without a spike. I have also lost all my weight and that really didn't help me with my IR. I think metformin has a lot of positive properties, such as cancer prevention, which I like.
