Sweet drink makes redhead feel unwell, I hear (6,3)
I believe the answer is:
ginger ale
'sweet drink' is the definition.
'ginger ale' can be an answer for 'drink' (ginger ale is a kind of drink). I am not sure about the 'sweet' bit.
'redhead feel unwell i hear' is the wordplay.
'redhead' becomes 'ginger' (I've seen this in another clue).
'feel unwell' becomes 'ail' (I've seen this before).
'i hear' shows a homophone (sound like).
'ail' sounds like 'ale'.
'ginger'+'ale'='GINGER ALE'
'makes' is the link.
Can you help me to learn more?
(Other definitions for ginger ale that I've seen before include "Spicy, sweetened non-alcoholic drink" , "It won't make you drunk!" , "One drink" , "pop" , "Fizzy drink" .)
