I would talk to anyone you know that knows a good hypnotherapist. Preferably one that has studied a man named Milton Erickson. GO to them and ask how much it would cost to do a couple of sessions and have them make you a Cd that you can use.
I would also go to a sleep clinic. I had sleep apnea ( very bad case) I didnt notice much disruption in my sleeping but they said it was there. ( I had surgery to correct it) But if your body is craving it, you better check it out.
