She felt slightly nauseous(adj).
She felt slightly nauseated(adj)
That smell itself is nauseating(adj) for her.
Are all these sentences OK?
Are ‘nauseous’, ‘nauseated’, ‘nauseating’ adjectives?
Please comment.

They are all possible. However, I think I would more naturally say “nauseating to her”, and there needs to be some specific reason for the use of “itself” in the third sentence.

In this case all three words are adjectives. In other contexts “nauseated” and “nauseating” can be verbal.

Can I say: “That smell itself is nauseous(adj) to her.”?

I’d forgotten about the disputed usage of this word.
