By finding the cause of your insomnia you can probably start to easily eliminate your problem. I don't know enough about insomnia to give you guidelines on how to determine the cause, so I strongly suggest that you use a more knowledgable resource. On the other hand, I do know of a few ways that can help you beat insomnia.

Keep a set sleeping schedule; get up and go to sleep at as close to the same time as you can, everyday. This is hard on weekends, but especially getting up at the same time is crucial to your good night's rest. Going through a routine set of activities before retiring (washing, a cup of tea, etc.) is a good way to send yourself a signal that it's time to go to sleep; it gives a sense of closure to your day. Tell yourself you have done everything you need to do for today, and you may want to sum up everything you need to do tommorrow and tell yourself that all of those things will be taken care of tomorrow. If you are reading or watching t.v., make sure it too has some form of closure, so that you can forget about it and just sleep, instead of laying in bed, thinking for hours. Also, use your bed for as few other activities as possible, other than sleeping.

In many cases, insomnia is caused by stress, so it is important to relax when going to sleep. You can use a deep breathing routine;

-lay on your back, in a comfortable position (yoga's "corpse" position, or with your hands interlaced behind your head, or however feels comfortable and natural to you)

-breath in slowly, but not neccesarily deeply (this can be very energizing), through your nose and then breath out, also slowly but not forcing yourself to get rid of all the air in your lungs, through your mouth (watch someone sleeping, mimic their breathing pattern and make allowances for the difference in lung capacity etc.)

-feel your toes relaxing,then your feet relaxing and sinking into the bed, your ankles, lower legs, your knees, and so on, covering every single body part in detail (it may be rare make it to your head!)

Another way to relax is to simply wiggle your toes for a few minutes. Your feet have tons of nerve endings, coming from every part of your body. Wiggling your toes stimulate, and thus relaxe, the nerve endings and the part of your body connected with each nerve ending.

You know how good it feels to stay in bed and sleep a little while longer early in the morning, when you have to get up and start the day? Imagine that it's time to get up, out from under the comfort of the covers, put your feet on the cold floor, start moving your tired, stiff joints, get your eyes used to the painful lights, get that morning taste out of your mouth, and do all the other unpleasant things that you have to do to start your day. Visualize this in every possible detail, and soon you will fall asleep, "just for a few more minutes".

One last thing you can do is to look forward to your dreams. If you follow the guidelines in the first paragraph, take your time in waking up (alarms are harmful to remembering dreams), and especially if you take a little time to think about the meaning of the dream (it is a worthwhile investment of your time and money to buy and read a book on dream interpretation ["dream dictionaries" aren't as helpful as a book that will also teach you the principles of dream interpretation; Jim & Pat Fregia's "Know Your Dreams, Know Yourself" is a great book]) then you will remember your dreams surprisingly often.

Well, that's all I have to say right now. Any other suggestions would be greatly appreciated; send them here.
