One should make you better fudge (6)
I believe the answer is:
doctor
I believe this clue is a double definition.
'one should make you better' is the first definition.
(a doctor makes patients better)
'fudge' is the second definition.
(fudge can mean to manipulate or doctor)
(Other definitions for doctor that I've seen before include "Medical professional or university don" , "Falsify; quack" , "An apple a day keeps him away" , "bones" , "One treats the ill" .)
