Twist article and employ another? Edward is sickened (9)

I believe the answer is:

nauseated

I'm a little stuck... Click here to teach me more about this clue!

'is sickened' is the definition.
(I've seen this before)

'twist article and employ another? edward' is the wordplay.
'twist' is a reversal indicator (I've seen 'twisting of' mean this (letters twist back)).
'article' becomes 'an' (English indefinite article).
'and' is a charade indicator (letters next to each other).
'employ' becomes 'use' (synonyms).
'another? edward' becomes 'ated' (I can't justify this - if you can you should give a lot more credence to this answer).
'an' written backwards gives 'na'.
'na'+'use'+'ated'='NAUSEATED'

Can you help me to learn more?

(Other definitions for nauseated that I've seen before include "Sickened" , "Revolted" , "Disgusted" .)
