Sedate, staid (5)
I believe the answer is:
sober
I believe this is a double definition.
'sedate' is the first definition.
(synonyms)
'staid' is the second definition.

(Other definitions for sober that I've seen before include "Snot drunk" , "Staid; clear-headed" , "On the wagon" , "Sedate and rational" , "Restrained, grave" .)
