In the end, will you miss much person drinking a lot? (4)
I believe the answer is:
lush
'person drinking a lot?' is the definition.
(lush can informally mean a drunk)
'in the end will you miss much' is the wordplay.
'in the end' suggests the final letters.
The last letters of 'will you miss much' are 'LUSH'.
(Other definitions for lush that I've seen before include "Succulent - alcoholic" , "dipsomaniac?" , "Lavish - boozer" , "Fancy" , "Habitual drinker (slang)" .)
