Dizzy
Based on what you were saying about the carbs I would say that you are having low blood sugar. I have the same problem. My doc suggested that I add a portion of fruit to my diet everyday. Even though it has carbs...it is all natural. It has helped me tremendously. Another suggestion, borrow someone's glucose tester and check your blood sugars. My doc told me every time I have an episode to test it to see it there is a pattern.
Hope that helps
