Hi. I am new to the forum. My A1C is now 5.5, down from 6.4...yeah! I am on 1000mg of metformin twice daily. As my last appt. (this week), my doc suggested adding actos to the mix. Has anyone begun this treatment? Is it supposed to be great for vascular reasons...but it causes weight gain. My weight is totally under control and I exercise a lot. I am hesitant to take something that might distrupt my current physical balance. Suggestions? Comments?
