On the question of _nauseated_ vs. _nauseous_, I've always let
Merriam-Webster be my guide:
http://www.m-w.com/cgi-bin/dictionary
Main Entry: nau.seous
Date: 1612
1 : causing nausea or disgust : NAUSEATING
2 : affected with nausea or disgust
usage: Those who insist that nauseous can properly be used only in
sense 1 and that in sense 2 it 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 in sense 1 is much more often
figurative than literal, and this use appears to be losing ground to
nauseating. Nauseated is used more widely than nauseous in sense 2.
