Holisticdetoxer - I only wish I knew if it happened in other countries. I've never had the chance to travel out of the U.S.A., it would be interesting to find out though.
I live in a pretty rural area, so restaurant choices are limited. So, I suppose it only happens everywhere that I get a chance to eat, so it's not as though I know if it does happen anywhere else. It's not something I really want to experiment with either, nothing like being a couple of hours from home in unfamiliar territory and having to find a bathroom.
Anarie - I have had other foods make me temporarily ill. It is pretty rare though, and would be hard to pinpoint a specific item. I don't have any alcohol anytime, so I wouldn't know about the wine. I do have lunch meat pretty regular though and it doesn't bother me. I will have to start paying attention to all the extra ingredients and see if I notice any type of sulfite listed as a preservative then pay attention to any reaction I may have.
