From advert, I got a queasy feeling (7)

I believe the answer is:

vertigo

'feeling' is the definition.
(I have seen 'unbalanced feeling' mean 'vertigo' so perhaps 'feeling' could also mean 'vertigo')

'from advert i got a queasy' is the wordplay.
'from' indicates the answer is hidden within the clue.
'VERTIGO' is hidden within 'advert i got queasy'.

(Other definitions for vertigo that I've seen before include "Sensitivity to heights" , "source of imbalance" , "the Eiffel Tower effect" , "Trouble with heights" , "Feeling of dizziness generated by heights" .)

I've seen this clue in The Everyman puzzle in The Observer.
