Have you ever tried reflexology? It worked wonders for me in helping return my sleep patterns to normal.
I battled a terrible sleep disorder for about a decade and after trying almost every type of therapy without much luck, I got some remarkably good results by trying this simple at-home reflexology treatment. It's so simple, the first time I tried it, I didn't even think it had done anything till I went to sleep that night. That one quick session of pushing on my pituitary points of each big toe gave me the most beautiful eight hours of sleep I had had in years. It didn't completely cure my sleep problems, but now when I wake up in the middle of the night, I'll try this technique, and it generally works like a charm. Here's a link to a blog that tells you how to do it: [DLMURL]http://solework.wordpress.com/2007/11/14/reflexology-and-the-pituitary-gland/[/DLMURL]
Recently a coworker who had served in the infantry told me that he was waking up about a dozen times a night and couldn't get a decent night's sleep, no matter what he tried. I told him about this technique, and it worked great for him, as well. I'm very curious to see if it helps any other PTSD sufferers (my sleep disorder wasn't caused by PTSD, but I think it could share some similarities to the sleep problems folks on this message board suffer from).
One tip I've discovered is that the first few times you try this, you may feel a bit sick the next day. Apparently that's because the pituitary has been kicked back into gear and it's doing it's job again. So your body goes through a bit of a detox. Anyway, I've found that taking vitamin C the next day helps keep you from feeling sick the next day.
Let me know if this helps! I'm really curious whether it will work for others...
