No whiskey at this point (3)
I believe the answer is:
now
'at this point' is the definition.
(I've seen this in another clue)
'no whiskey' is the wordplay.
'whiskey' becomes 'W' (alpha bravo charlie delta ...).
'no'+'w'='NOW'
(Other definitions for now that I've seen before include "At this moment in time" , "Today" , "Immediately" , "straight away" , "The present moment" .)
