Nauseated, queasy (7)
I believe the answer is:
bilious
I believe this clue is a double definition.
'nauseated' is the first definition.
(I've seen this before)
'queasy' is the second definition.
(I've seen this before)
(Other definitions for bilious that I've seen before include "Queasy" , "Affected by illness, or just bad-tempered" , "Feeling sick" , "Nauseating" , "Liverish - irritable" .)
