<<Disclaimer: Verify this information before applying it to your situation.>> My wife is about to go on a skiing holiday to Austria. I have got hold of a German version of the description of Celiac Disease and what can and cannot be eaten from an Austrian web-site. She is worried however, that, despite best efforts, she will have an "accident" and wonders whether it is safe to use a diarrhoea "blocker" so as not to miss her skiing. (In UK we have a product called Imodium, which is pretty instantly effective.) Obviously she's not going to take Imodium before an accident as insurance, this is almost certainly a _bad_ idea, but is it OK to use it after? John
