I was on insulin when I was first diagnosed, but I kept passing out--so the Dr. stopped the insulin. I was supposed to take 20 units the first day--and my Nurse Practitioner wife suggested we start with just 2 units, because she knew that I had unusual reactions to med's. I passed out with just 2 units of insulin. Now I am on 850mg Metformin twice a day, no insulin. I strongly suspect that I may have the Autoimmune Diabetes, I believe it is called. They also call it 1.5 Diabetes for a shorter name. I read about it on the Mayo Clinic Newsletter I get through my e-mail. The treatment is mostly the same, the only difference is that eventually you will need insulin to control it; and most people who have it are misdiagnosed as a type 2 diabetic at first. I take it one day at a time, with a whole lot of prayer mixed in and leave the rest to the Lord!!!!
