Kaneki has a bad case of insomnia due to his mental illness and can't actually sleep most of the time! he usually trains himself into exhaustion until he passes out and this way he can "sleep" for a couple of hours.
IF ANYONE WOULD LIKE TO HELP WITH THAT it'd be awesome! Or just insomnia palls, that works too! Bad choices during sleep deprived is awesome too. It's also very possible to find him training or to find Kaneki passed out in random places.
