Get-well program, briefly (5)
I believe the answer is:
rehab
'get-well program briefly' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for rehab that I've seen before include "Restoration to health after, eg, addiction (colloq.)" , "Course of treatment for addicts" , "Training and therapy after drug abuse" , "Restorative care" , "Treatment for, eg, addiction" .)
