I was diagnosed with pre-diabetis for having an A1c between 6 and 6.4. My MD put me on metformin and told me to cut out carbs. After 3 months I went down to 6.2, but then my sugar's started going up and I couldn't figure out why. He increased my dose to 1000, 1X Am and 1X PM and now my A1C is 5.9.
Great to be within the normal range again!!
I also lost about 40lbs.
