I am a type 2 diabetic and have been since 1998. I was recently diagnosed with breast cancer and have surgery and have started chemotherapy. Since my surgery in January I have had trouble getting my morning fasting blood sugars below 200 they are usually in the 220 to 230 range. My family doctor now has me on metformin, glipizide, actos and januvia. The chemo temporarily raises my blood sugar levels. I have been eating a snack before I go to bed. What else can I do?
