Yes, alliswell!! Sorry to hear about your sleeping dysfunction -- as a fellow raving insomniac, I too suffer the malady.
You've probably tried everything I'm going to suggest, but if not, maybe one of these tips might be useful.
I find that whenever possible, lowering the lights, turning down ambient sounds, and blithering myself into a stupor with a mindless but non-exerting activity helps. A small dose of soothing liquid or a comfort food may also do the trick, if consumed in a relaxed position like a couch or easy chair, rather than totally upright at the dining table. Remove all constricting garb as well.
Anything that can help lower sensory stimuli and heart rate also works, if you try to empty your mind, ease your anxieties and keep the body as relaxed as possible. Other times, it's also a matter of disciplining yourself to try to get to bed at the same time regularly.
Mostly, though, when completely done in, I just collapse in front of the TV screen and pass out for the night!
