he can work 24 hrs a week & go to school full-time & think he can get by with 4 to 5 hrs sleep every night and still function with no problems. He has to sit thru class all day he has a full load & wants to hang out with his friends & go to parties every chance he gets.Now all of a sudden he has al these dents & scrapes on his car & has the most unusual stories about what has happened. What can I do to help him see that this is a very bad for his health & life? He comes in anywhere between 2 to 3 am. He wakes me up everynight to let him in as I lock my screen door. He is also disrupting my sleep and I have to be at work @ 8am.
