Oh, okay! Play time! Figure out what kind of games and or toys he likes - whether it is fetch games, batting around toys that make noise, "fishing pole" type toys - it may take some persistence and experimentation, but you should be able to find something! Then play, play, play before your bedtime, a worn out kitty is a quiet kitty! Have you tried taking him out for walks on a harness and leash? Any physical and mental exercise will help!
