Hi again. Here is a website that has lots and lots of information for you.
http://www.bloodsugar101.com/I suggest keeping a food journal with time/meal and what you eat and your blood sugar before eating and about two hours afterward. In this way you'll see how your blood sugar reacts to the food you eat.
You need to strive to get your blood sugar lower in order to prevent health complications later (heart, kidneys, eyes, circulation).
I don't know how to tell you to get activities in. Maybe your doctor can do that. Have you been to rehab?
