I am familiar with that feeling when you just can’t sleep for a long time and on the next day feel yourself absolutely shattered. I know why it happens, but still have such problems from time to time. Having a lot of thoughts in my head can cause sleep problems. Other causes are watching an exciting movie, playing computer games, internet surfing and coding. The cure here is to wake up early and to go sleep early, to stop any exciting activities and to relax before going to bed.
