Ted, I don't know what you have in mind.
I've looked up nauseous at dictionary.com, and here is what it says:
1. affected with nausea; nauseated: to feel nauseous. 2. causing nausea; sickening; nauseating.
Merriam-Webster.com lists the two definitions in the reverse order:
1 : causing nausea or disgust : nauseating
2 : affected with nausea or disgust
I hear many people use "nauseous" when they have nausea. Merriam-Webster lists the first definition for "nauseous" as causing nausea.
Of course, the whole dictionary definition, "language is a living, changing thing" discussion gets tedious very quickly.
Oh, and just to get the thread back on track: Boy, what about that divorce settlement? $750mil sure is a lot of scratch!
