Anyone's food tolerances turning into allergies? One of mine was garlic. If I ate a lot of it I felt a little sick and sometimes had diarreah the morning after (had to be a lot). Now I have the slightest amount at all and I wake up with a migraine at midnight, followed by diarreah, few vomits and overall heavy sick feeling. Is it unusual for this to be magnified to such an extent? Has anyone else experienced this?
