Insomnia can be the result of different reasons. Insomnia might appear if you are worried about something, because of medical issues or you have slept all day. If I can't fall asleep, I read a lot. Heavy reading is really helpful, something like Nietzsche or Schopenhauer, after the second page a sound sleep is guaranteed. :)

Insomnia can be managed by 1) hot bath 2)Radio 3) newspaper and not a textbook 4) a glass of milk before sleep 5) no TV before sleep 6) no coffee or tea before sleep 7) regular sleep on a constant time for example 11pm every night 8) after 20 minute after going to bed , if you can not sleep then go to do some thing else as reading news paper and after get sleepy return to bed 9) do noy do your home work or daily tasks in your bed , use your bed only for sleeping 10) if your sleep not recovered , you must take a drug for example zolpidem 5mg Tablet / one tablet 1 hour before sleep .

see your doctor!

stay quiet,and lay on a comfortable position,Meditation is a good plan.Try to recall something long long ago,more details such as some words or your felling，and you will get sleepy
