Exhausted everything included (3,2)
I believe the answer is:
all in
This clue is a double definition.
'exhausted' is the first definition.
(thesaurus)
'everything included' is the second definition.
(I've seen this before)
(Other definitions for all in that I've seen before include "Weary" , "Absolutely exhausted" , "expenses and costs included" , "Inclusive; tired" , "price covering the lot" .)
