WOW, I’d be jumping up and down with a 5.4 A1C!!! Good for you!
I’ve been on 2000 mg of metformin for about a year (1000 am; 1000 pm) I didn’t have any of the side effects that they talk about, and that I am happy for. However, I do take it with food, and that I think helped with the stomach upset. I also take amaryl and januvia with it, and that’s been going good too. My sugars were uncontrol until I got a cortison injection for my arthritis, and then we whacked out…but getting back to normal is a good thing. As far as weight gain/loss, I found my appetite was much less with the metformin, and I didn’t NEED to have something sweet after dinner…that was great! Good luck with it, let us know how you are doing.
