Did your doctor prescribe a food class? This is the number one type of education you need. Call his office and get one ordered if it's covered by your insurance. If not, check into teaching by local nursing schools or nearby universities. You can often find eating plans from your local health department, also. If your doctor is only offering medication without patient teaching I would find another doctor, hopefully an endocrinologist. You have a long and happy life ahead of you if you get the correct information on how to handle your glucose levels and all the problems they can lead up to.
One positive thing you can do is start a food, diet, exercise journal. Doesn't have to be anything elaborate, just jot down your blood sugar readings in the morning and before dinner, jot down your foods as you eat them, if you exercised and how you're feeling. In a few weeks you will have some real information you can use in your life. This was how I found that I am extrememly sensitive to potatoes and rice but not so sensitive to corn and wheat. They are all carbs but my body thinks that rice is candy! I'm able to adjust my eating patterns so that when I have these foods I am careful to limit them. When I eat Chinese, I use the rice like a condiment, putting two tablespoons or so on top of my meat/vegetable mix. I only eat little bitty baked potatoes and limit myself to 13 french fries when they are part of the meal. All the diet books in the world wouldn't have been able to figure this out for me. I had to use my personal experience to plot my own course thru the food mine field.
You can do your own research and do very well also. Hang tough, buddy. You can get there from here and we will help!
