Without drink he'd get cured (6)
I believe the answer is:
healed
'cured' is the definition.
('heal' can be a synonym of 'cure')
'without drink he'd' is the wordplay.
'without' indicates putting letters inside.
'drink' becomes 'ale' (type of beer).
'ale' inserted within 'hed' is 'HEALED'.
'get' acts as a link.
(Other definitions for healed that I've seen before include "Became healthy again" , "Made well" , "Cured, mended" , "Cured, recovered" , "Mended, recovered" .)
