Those who insist that nauseous can properly be used only to mean “causing nausea” and that its later “affected with nausea” meaning is an error for nauseated are mistaken. Current evidence shows these facts: nauseous is most frequently used to mean physically affected with nausea, usually after a linking verb such as feel or become; figurative use is quite a bit less frequent. Use of nauseous to mean “causing nausea or disgust” is much more often figurative than literal, and this use appears to be losing ground to nauseating. Nauseated is used more widely than nauseous when referring to being affected with nausea.
Most seafood doesn’t get me too badly, though I still don’t like it. Cooking shrimp, on the other hand, makes it hurt to breathe for some reason. Not the same as nausea, but it still sucks.
Literally anything that smells like seafood will make me nauseous
Nauseated. Though as an American I’m about ready to give up on this crusade. Nauseous means you make others want to vomit.

Sounds like you’re allergic to shrimp.
