I'm no doctor, but if you are really willing to make those lifestyle changes, at your age and that A1c, I would tell them you want to give it a try for 6 months with diet and exercise before putting you on metformin. Won't go into my personal experience more than to say, had a Dr. throw me on metformin a few years ago and I just went along with it. My current and new Dr. is looking to take me back off of it now.
