I'm currently on metformin once a day. Iv had lots of stress and worry and it has gradually been creeping up. I had bloods back today and I have very low folic acid and hb1c of 63. Not good. I have an appointment with the diabetic nurse next week. I worried about what might be the next course of action. I need it to come down just don't want to have to go on insulin. Does anyone have any advice to reassure me
