I agree that after a while you will be able to tell. About 30 years ago my Dad was also told he had diabetes. We all took the new serious as he had a brother who died from the complications even though he did all the doctors told him to do at the time. Dad followed the "exchange" diet to the letter. We all found that weight was a key factor. If your weight went up, your sugar wasn't under control. Energy was another factor, too much carbs and a nap was in order. Our Wellness Center gives out guides to carbs, fats, etc. Also we found various sites on line that aid in counting and allow you to input what you've eaten for a nutritional breakdown. The 6.95 IS a good price but if tight on time you may want to "google" and check-out some on line sites. It would also give you some others to discuss the diet issues. Also don't forget that activity factors into what you can eat just like anybody's diet! Good Luck, it does get better and you'll feel better also!
