I'm type 2 diabetic, diet controlled, and my sugar levels r in the 200's and I had a headache for 2 days now. What should I do?

diabetes. Apparently diet is not enough because glucose level is still about 200, beside diet and excercise, an oral medication is probably needed at this point; talk to your doctor about the headache.
See below. You need to see your doctor and review your diabetic control. You may need to start an oral medication such as metformin.
