Hi Ginger. Was just skimming your thread. I've been here a long time too. (11 yearsish) I'm also on Metformin and Insulin. The Metformin messed me up for a while, but the doctor just told me to take half a dose. Everything "cleared up" after a week or so. I was just taking too much of it. I may have missed it in your post but are you still on it? Have you tried a lower dose?
