Hi luna,
I too found that the calm music effect wore off after a while....
I started reciting things to myself before sleep. Particularly the opening credits to 'Bagpuss'. It is that childhood, familiar, comforting and cosy sense of repetition that lulls me to sleep. I picture the scenes, and I can almost hear the old chap saying the words...
"There once was a little girl, and her name was Emily. Now Emily had a shop. It was a very unusual shop, because it didn't sell anything. Everything in that shop was a thing that Emily had found, and taken home to Bagpuss. Emily's cat Bagpuss. The most amazing, the most incredible....saggy old cloth cat in the whole wide world..... Now one day, Emily found a Thing. She took it home, laid it in front of Bagpuss, and said some magic words. 'Bagpuss, dear Bagpuss, old fat furry catpuss. Wake up and look at this thing that I bring. Wake up, be bright, be merry and might, Baguss O hear what I sing'. And when Bagpuss wakes up, all his friends wake up too. The mice on the mouse organ woke up and stretched......." etc etc!!

Copyright Bagpuss, obviously lol.
I found getting back into the habit of falling asleep the hardest thing. Once I'd cracked that a few times, it was easier. I think you just have to find what works for you. I love Bagpuss, I have a big, huggable Bagpuss. Aww bless.
All the best,
Bram.
