Without testing I don't know if you can assume celiac from this timing sort of thing.Sometimes if we "know" we shouldn't eat something. And by "know" I mean the brain has "decided" (this is not concious it is more like Pavlov's dog sort of thing) that X food makes us sick and must be tossed out of the body if it is ingested.I had this with raisens and it made no sense that there was any food intolerance mechanism (grapes, fine, all other dried fruit, fine, raisens...instant vomit). After a few years of avoiding raisens totally I got over it. But as long as I ate raisins it kept happening. And that sort of reaction fits the timing. You eat it, the brain signals the mast cells and they expel the stuff from the body.That is just one explaination if nothing pans out with it. I was on a field study with a celiac who was really sensitive to gluten (I mean if you stuck a spoon in the regular pasta and then put it in the gluten free pasta he would react) but it wasn't a 10 minutes later he was violently ill like this...I think with him it seemed more of a couple of hours later, I thought (and I could be wrong) that it needed to hit the small intestine before the sort of recognition of the gluten would occur.In any case I hope you feel better soon, I would run this past the doctor to see if they want to do tests for celiac (I just don't know if this reaction would be typical of celiac, it doesn't from the person I know, but that doesn't mean it isn't in the realm, I would think if this was typical for celiac it wouldn't be so hard for people to figure out what is going on with them.) and for now, stick to the diet that doesn't make you sick.
