Welcome Tiger, you are in a great forum.
I have Diabetes Type 2, as well. You need to keep your numbers between 90-140. A lot of people with Type 2 keep within a closer range: 80-120.
You need to watch your serving sizes. If a box or bottle says 1/2 cup serving size, measure it and stick to it. Watch the carbohydrates!! You should only have no more than 150 carbohydrates per day. Use only non fat milk and non fat yogurt is a great dessert with a tablespoon of preserves and a few nuts with it.
Check your blood sugar before each meal. That way you will know whether to eat more or less. If it is high, eat less. Not eating is not good. Then 45 minutes after you eat, exercise. Between lunch and dinner is when my bg is high, that is when I need to exercise.
Fasting will mess up your numbers. Plus, it makes you more hungry for lunch and you eat more then.
I hope I have been of help. I have the same problems with doctors. Ask to be referred to a really good nutritiionist!! Check out the diet section of the forum.
