My 23 year son lives on his own. He sleeps and plays games sporadically throughout the day and night. I have been trying for 9 months to get him to go to sleep at night and set his alarm to wake up in the morning so that he can do things during the day. Nothing has worked and I am thinking of getting him a flip phone so that he can't play all night. I am open to any ideas and if changing to a flip phone temporarily makes sense. Thank you.
