Stretched out drunk (5)
I believe the answer is:
tight
This clue is a double definition.
'stretched out' is the first definition.
(thesaurus)
'drunk' is the second definition.
(I've seen this before)
(Other definitions for tight that I've seen before include "with limited room to manoeuvre" , "Fast - affected by drink" , "high tension" , "Squeezed" , "Close - drunk" .)
