Dealing with Alters Switching Intensities

How do you handle different intensities of alters switching around? For me, in the morning, everyone is very quiet and/or just waking up. Everything is alright, and it's nothing too crazy. In the afternoon, things start to settle in a little more. There are prominent alters here and there, and they switch around just fine. But when the evening or late night rolls around... The whole system goes almost haywire. Alters are switching around so much, and sometimes it's even hard to keep track. It's almost like everyone wants to speak at once, but can't (for clear reasons). How do you handle with that sort of stuff? The only way I've been able to is to just let everyone do their thing, or try to not let everyone get too hyperactive. If you have advice, it'd be so appreciated. -Elias (the eternal self helper)
