Tip for going to sleep early. Cut out all rituals, or do them early in the night. Then lie on couch with a book or sefer, and fall asleep the natural way. After an hour or two, run to bed and sleep soundly.
Trying to force yourself to go to sleep never works. Worst is the day before a big interview or flight or something. Many times you will not be able to fall asleep under that pressure. But the couch really works.
