Dissatisfied (3,2)
I believe the answer is:
fed up
'dissatisfied' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for fed up that I've seen before include "Surfeited" , "far from happy?" , "Disgruntled (colloq.)" , "offered in-flight catering?" , "Bored - disgusted" .)
