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?

Do you exercise anytime during the week?

In a period of my life I was doing (about a week and about 10 minute a day) of course not hardly but it doesn't any effect. Is it low?

See a physician. Ask to be tested for sleep apnea, nutritional deficiencies and whatever else the doctor suggests. I have been "oversleeping" since the age of 4. I used to come home from pre-school and voluntarily take a nap. Years later, it was discovered that I have Multiple Sclerosis. I doubt that you do, but ask the doctor plenty of questions.

You may have narcolepsy. This is when a person sleeps too much and can fall asleep while doing simple tasks unannounced. Your doctor should be able to help you.

I swore I was narcoleptic I could even fall asleep driving.
I became aware of my sleep/awake/exhausted/and 'numbing out brain fog' patterns and corrected them by changing my eating habits got more nutrition taking supplements.
Sleeping on a scheduled pattern is also helpful.
Also don't over exert yourself. Even with a hectic schedule it is important to relax and not overwhelm yourself.

Thank's for answers.I must solve this problem as soon as possible because I am trying to enter the university and doctors say to me that it has not any cure.when I sleep low I can't study my lesson with
Good quality...

If you take meds you have to check if it is okay to take magnesium and potassium

I take B complex in the morning after breakfast
And at night I take 600 mg calcium, 300 mg magnesium, potassium and vitamin D3
It takes a couple weeks to notice a difference.
If I skip some days I notice how much tireder I get.

Thank you very much specially ((N0help4u)).I am waking good and in time in a few last days I hope it continue because in the past I have experienced this but after a week it has backed to it's usual way of course I didn't use the things and vitamins that you have wrote.thank you all.
