As before, not all recommend it totally (5)
I believe the answer is:
ditto
'as before' is the definition.
(ditto means the same as previously mentioned)
'not all recommend it totally' is the wordplay.
'not all' indicates a hidden word.
'DITTO' can be found hidden inside 'recommend it totally'.
(Other definitions for ditto that I've seen before include "Two dots indicating the same again" , "Likewise" , "Repeat the word above" , "The same thing" , "In lists, the same again with two small marks" .)
