This is exactly what I am experiencing at the moment. If I eat any kind of foods that are high in sugar content, I react very badly to everything I eat. Yesterday, I took a bit of mango. Yes, it was good and very juicy and sweet. No, I am really paying for it. Have terrible headaches, stomachache and my intestines is killing me. Does anybody have any suggestions on what I should do to relieve this awful pain. Thanks to all. Clelia
