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