Fully satisfied (5)
I believe the answer is:
sated
'fully satisfied' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for sated that I've seen before include "Stuffed with food, too full" , "Indulged to the full" , "Stuffed with dates" , "Replete" , "Stuffed, having eaten to the full" .)
