Drunk omits abuse getting sober (10)
I believe the answer is:
abstemious
'sober' is the definition.
(thesaurus)
'drunk omits abuse getting' is the wordplay.
'drunk' indicates anagramming the letters.
'getting' says to put letters next to each other.
'omits'+'abuse'='omitsabuse'
'omitsabuse' with letters rearranged gives 'ABSTEMIOUS'.
(Other definitions for abstemious that I've seen before include "in a way that's restrained" , "I mess about (anag.)" , "not eating or drinking a lot" , "Self-denying" , "Indulging only moderately (in food/drink)" .)
