Oh I won't allow any shellfish, onions, or garlic in my house at all! (Big triggers for me!) I know what you mean for sure! My husband gets it, too. If we are out at a restaurant and he eats shrimp or any other shellfish, he knows to go wash his hands immediately and not to touch me or my food until he has scrubbed! I have thought to myself about what if he breathes on me just while speaking? Thus he has to keep his distance even just as we continue to eat dinner. I notice that I cannot stand the smell of any shellfish now (and I used to love it before I got ill). I think this is my body's self-defense mechanism coming into play by making me despise the aroma. Needless to say, hubbie doesn't eat shrimp much! LOL
