The main thing to do is turn off the tv. That's number one. Keep iPhone, iPad use to a min. That's why most of the population can't sleep, all we do is watch tv and get on our iPads at night. The rest is up to you, you can read a book, another method is to listen to movie or video, something with your eyes closed. Thats proven to make you fall asleep kind of like a kid getting read a bedtime story. Also telling yourself ahead of time you will sleep helps too, it's telling your mind subliminally. They say your body listens to you.
