Accepted being sent back to find healthier hot drink? (5)
I believe the answer is:
decaf
'healthier hot drink?' is the definition.
'accepted being sent back' is the wordplay.
'accepted' becomes 'faced'.
'being sent back' says the letters should be written in reverse.
'faced' back-to-front is 'DECAF'.
'to find' acts as a link.
(Other definitions for decaf that I've seen before include "Cup substitute missing kick" , "Non-alcoholic drink" , "Type of coffee" , "Less stimulating coffee?" , "Style of coffee" .)
