Can anyone recommend a good relaxation CD ?

Hi Folks,
Question in the title really. I wake up at night with my brain in overdrive and can't get back to sleep for hours, tossing and turning.
I would love a relaxation/self hypnosis cd (not weightloss) that I could use to try and calm down and get back to sleep.
Any suggestions ?

I'm not sure if this is much help, but I like panpipe music, I think its quite relaxing. Or Chill radio on dab radio???
