caregiver222's advice is logical. If for some reason you can't afford the test, try the Slow Carb Diet. The name is misleading, it should be called the Slow Carb Nutritional Program! You can stay on it for the rest of your life! If you own an iPhone - the apps are free online. You can order it online as a hardcover or an eBook. Basically, you can everything except for "White Carbohydrates" .... Bread, potatoes, fruits, rice & noodles - for example!
