It must be awful olddude to lie awake hour after hour and be unable to drop off, I do feel for you. I'm lucky and can sleep for Britain. But I wonder if you do enough during the day to make you tired? If you're fairly inactive, you don't need that much sleep. Also, I find tons of fresh air in the bedroom (ie not stuffy) is a good thing. Also, don't eat just before going to bed. And don't watch over-stimulating programmes on TV. I have a dear friend who can never get to sleep. She makes herself get up out of bed if sleep won't come, and only goes back if she feels a bit more sleepy. I wish you well, as I know, like my friend, it must be pretty miserable for you.
