When I can't sleep, I do something which I call the '1 2 3 4 5'-exercise. While still in bed, lay on your back and think of something you can 'see' (imagine it), anything as long as it's something that physically exists. For example: your car, a guitar, a chair. Imagine it and try to describe it to yourself in the best possible detail. 'My guitar is surf green, it's a Fender Carbonita, it has 22 frets, it has a maple neck, ...' Do this for five things. Then move on to "things you can feel". Physically feel. For example, describe how your couch feels, how your blanket feels. Again, every little detail. Five times. Then think of five things you can hear: not at that exact moment in your bed, but things you might have heard throughout the day. Something I think of often is the sound of a train arriving or leaving. Again, try to describe it to yourself in the best possible detail. Do this, again, five times. Then start over at describing something you can 'see'. Do it four times, move on to feeling, 4 times, move on to hearing, 4 times. Then all over again, except this time 3 times. Then 2, then 1. I have never made it past the first 5 descriptions of 'see'. I usually fall asleep after describing two objects to myself. It might help you fall asleep.. Might not. Worth a try, perhaps?
