Drink drivers perhaps raised fuss (4,4)
I believe the answer is:
club soda
'drink' is the definition.
(I've seen this before)
'drivers perhaps raised fuss' is the wordplay.
'drivers perhaps' becomes 'clubs' (driver is a kind of club).
'raised' says the letters should be written in reverse (going up in a down clue).
'fuss' becomes 'ado' (synonyms).
'ado' reversed gives 'oda'.
'clubs'+'oda'='CLUB SODA'
(Other definitions for club soda that I've seen before include "Carbonated water (US)" , "Fizzy drink" .)
