Hi-I've been fighting the battle for only two and a half years but have been on Metformin for the duration. I have lost 30 lbs since I first started and my A1C has gone from13.9 (aaaggghhh) to 6.4. I don't watch my diet as well as I should but were I 30 instead of 70, that may have been different too.
I have had no problems with Metformin-other than some stinky gas, but what the heck, late research has said that is good for you too!
Good Luck with finding the medication that is right for you-in the meantime, work to take off some weight-that definitely helps, and enjoy this great life!
