im currently having to change my diet as well to get my blood sugar down. I had already cut out sugary foods etc but have now been told that some carbohydrates are better than others and doing things like eating wholegrain cereals and having brown bread are supposed to help you get better control. My doctor said he is going to refer me for a carbohydrate counting course to help me understand more about it, maybe this would be beneficial for you as well?
i hope i was of some help.
