I was a type 1 diabetic from 1945 until the 1990s while using animal insulins. Then synthetic insulins entered the picture. I was counting carbs and getting plenty of exercise, but I started gaining weight, and did not know why. I was having to use much more insulin than before. My teaching at the community college was not good anymore, I had lost my ability to be a good teacher. I retired at the age of 57 in 1997. My doctor diagnosed insulin resistance, and in 1999, I started using a type 2 med, Avandia. My resistance decreased, and so did my insulin dosages. I felt much better and taught part time for several years. Avandia was found to cause heart complications for many users and was banned in many countries. My endo then prescribed Metformin. I had been reading more and more about type 1 diabetics who were using Metformin for isnulin resistance, and was anxious to give it a try. I had no complications with Metformin ER and took 1000 mg both AM and PM. I started losing weight, and during the first 14 months of using that med, I have lost 22 pounds. Now I am only one pound above my ideal weight.
Metformin has helped me very much, but my control is not as good. My weight has stabilized, but the range of my BG's has increased. I am having more lows and highs that before. Adjusting many things, especially basals and ratios on my pump, has not helped very much. I have an average of two lows in the 35-55 range each day, and they can occur randomly and show no consistent pattern. I have adjusted to these lows, and never need any help with them, but I really need to find some way of avoiding them. I really need to improve this situation, and stop having so many lows. My spring and summer schedule is going to be hectic with working on my house and doing a lot of sanding and painting. I insist on taking a lot of long walks and working out at the local gym. Staying in good physical shape is an obsession of mine. I am very active, but that is part of the reason I have these lows. I must try and have my schedule become more consistent and find a way of keeping my BG above 60. It won't be easy, but that is my challenge for the rest of this year.
