I don't have too much trouble with staying up too late, but I do sleepwalk and sleeptalk, and wake up a couple of times a night for a while before going back to sleep.
I also slept a lot of nights with my mom in her bed, sometimes every night for months. I just felt safer in her bed. I kept doing this until she got married when I was 16. If she hadn't gotten married, I would probably still be doing it.
