Hedonist a bit inhibited by 'hedonist's complaint' (8)
I believe the answer is:
gadabout
'hedonist' is the definition.
'a bit inhibited by hedonist's complaint' is the wordplay.
'bit' becomes 'dab'.
'inhibited by' means one lot of letters goes inside another (I've seen this in other clues).
'hedonist's complaint' becomes 'gout'.
'a'+'dab'='adab'
'adab' inserted within 'gout' is 'GADABOUT'.
(Other definitions for gadabout that I've seen before include "restless type" , "Person who goes around aimlessly" , "Restless seeker after amusement" , "restless sort" , "Person who wanders aimlessly in search of pleasure" .)
