Sorry, I did add that I get these feelings regardless of the carb content...I feel that way no matter what I seem to eat.
I eat and shortly after ...brain fog and fatigue.
I eat almost no grains, and absolutely no dairy or gluten. Very little fruit, very little honey, virtually no sugar.
This doesn't fit with Reactive Hypoglycemia, or does it?
Though you mentioned food intolerance...I've thought myself that may be the case..how can I find out for sure?
Aside from all that, can I have an under-functioning thyroid rather then full out clinical hypothyroid?
