I sometimes sleepmore than 11 hours and but I like to sleep more.sometimes my clock alarms all one hours and I listen nothing! If I wake up at 10 AM today I can hardly wake before than 10 the next day and it not depend that when I go to bed it's last night.just if I don't sleep a complete day I can set my waking time and being 24 houre awake is so difficult for me because I must study more than 6-7 hours a day for entering to university.please help me and say to me is there any cure for my problem?
