What is so confusing is that the reactions are not often - I haven't had another this year until last night, then I might have several in a short space of time. I was tested for MSG as I really thought that was what it was as my first reaction was after eating at a chinese many years ago, but nope not even a minor indication to that. I also thought it was seafood, nope, not that either.
I guess I haven't done anything further about it because the specialist sat there and basically said that was it, he couldn't explain it, and had no idea what else to do - almost felt like he thought it was in my head!
I will check out that book, thanks Yael.
