Satisfied, having journalist calmed down (7)
I believe the answer is:
sedated
'calmed down' is the definition.
(I've seen this in another clue)
'satisfied having journalist' is the wordplay.
'satisfied' becomes 'sated' (I've seen this before).
'having' indicates putting letters inside.
'journalist' becomes 'ed' (short for editor).
'sated' enclosing 'ed' is 'SEDATED'.
(Other definitions for sedated that I've seen before include "Drugged" , "kept calm" , "Given calming drugs" , "Under the influence of drugs" , "Calmed with drugs" .)
