Has anyone ever suddenly had thier Diabetes go out of control? Mine has been pretty well under control for about 3 - 4 years. All of a sudden I can't get it under 220. We've upped my metformin to 2000 mgs and added a drug that should produce more insulin (yesterday) but so far its still high. 4 hours after lunch - 350. Now admittedly I had a "normal" lunch - a foot long subway sub. But all it had on it was turkey, lettuce, tomato, cucumber (being different) and some carrots. Nothing else and diet coke to drink. No chips, no dessert.
