Exercise in a fixed routine can help. Stay away from TV, since it puts you in a semi-comtose state anyway (in many cases) and acts as a sort of sleep substitute. For some reason, reading is way better, and for this purpose, a book that interests you but that you find heavy going. Dwight Eisenhower's "Crusade In Europe" or something like that might do it -- the vast detail leading up to D-Day, interesting but also lulling. When you actually get down, a little methodical hyperventilation like inhaling and exhaling on a long count (for you, whatever that is) often makes you drop off. Meantime, look around for a good sleep disorder practice, which isn't easy to find. A lot of these pro's address the generic problem without addressing the patient him or herself, so you have to select carefully and be your own doctor after a point. A lot of the meds just confuse the issue, and you don't know what kind of sleep you're getting if you do sleep. Soaking in a hot bath and submitting to massage may also help. If you can't sleep, get up and do something, don't just toss, and then try again when you feel more drowsy. Nearly all of us need more sleep than we get, so you aren't alone.
