" I was noticing during living in Hawaii that I would become chronically fatigued and sleepy after eating. It was strange, as it did not happen at every meal. I would eat at the same restaurants and sometimes I would be sickly after eating and other times I would feel fine. I knew I had past food intolerance to gluten, fructose and lactose and was avoiding them. But even with this avoidance, some meals would make me sickly! It was a mystery I could not understand, no matter how much I tried. The only clue I had was it seemed to occur only when I ate large meals. I could eat small meals fine anywhere, but large meals were an occasional issue. "
