Her good faith sorted out answer to alcohol problem? (4,2,3,3)
I believe the answer is:
hair of the dog
'answer to alcohol problem?' is the definition.
('hair of the dog' is a supposed hangover cure)
'her good faith sorted out' is the wordplay.
'sorted out' indicates anagramming the letters.
'her'+'good'+'faith'='hergoodfaith'
'hergoodfaith' is an anagram of 'HAIR OF THE DOG'.
(Other definitions for hair of the dog that I've seen before include "Morning tipple after night of excessive drinking" , "Hangover-curing drink" , "Alcohol taken to "cure" a hangover" , "Same drink the morning after" , "Maybe one in the morning" .)
