ENGLISH: Simply remove all unnecessary stuff from your bedroom (book, papers, etc.) Books and other stuff don't have near your head! Remove all working stuff, papers, bills etc. from your bedroom.
Clean your bedroom, and try to rotate your bed and yourself in position legs north and head south.
There's some flow from the north, position "legs north head south" could significantly improve your sleep. In the morning, when you once get up, don't get back into your bed. Good night, God with you.
