Got into a bed, drunk (8)
I believe the answer is:
obtained
'got' is the definition.
(obtaining is a kind of getting)
'into a bed drunk' is the wordplay.
'drunk' is an anagram indicator.
'into'+'a'+'bed'='intoabed'
'intoabed' is an anagram of 'OBTAINED'.
(Other definitions for obtained that I've seen before include "Acquired" , "Into a bed (anag.)" , "Got, procured" , "Came into possession of" , "Got something" .)
