Hi again, Amy
If you are feeling that your blood sugar is low, that may well be because you are having an insulin reaction to too many carbs. Have you tried any of the low carb protein bars, when you "crave" sweets? Some of them are chocolate flavored, and quite good - they give you protein that your body can use and do not produce the insulin triggered high & low blood sugar. Another idea is Gatorade which is one of the sports drinks that is low in carbs - only 5-6% I think, which is a lot better than many of the others. Anyway, you will have to experiment to find out what works for you.
Best of luck.
