Avalon, you have done so well, and you are a real inspiration.
I assume your secret is good diet and exercise, and keeping at it. You should not think that staying on metformin means you have not been successful in dealing with T2. But once we have it, we are never truly cured. YOur pancreas and liver will still think like you have diabetes, and sugar spikes can cause microscopic damage that metformin really helps prevent. I don't really plan to go it at my age, personally.
Keep up the good work, and work with you doctor. I am so impressed and inspired by you.
