I can tell when my son’s psychosis is gearing up because the first thing that happens is he switches from sleeping at night to sleeping in the day. He will work hard to get his hours straightened out and get a regular schedule going, just to have it all go topsy turvy. Mine has trouble sleeping when the psychosis starts ramping up towards a new episode. During a bad episode or psychotic break he doesn’t sleep at all. Which really makes it all worse.
