If I cannot use sleeping pills to sleep, how do I sleep. The CPAP macxhine does not let me sleep.

I hope that a sleep doctor can answer this question. I cannot use the CPAP machine because I have chronic anxiety and it bothers me. I have stopped using it for the last two years. Can you die from not using this? I went to a sleep psychiatrist for an evaluation and he said I have PSYCHOPHYSIOLOGICAL INSOMNIA. I need something for sleep and he said NO SLEEPING pill will work and he was right. I am lucky to get 3 hours of sleep per night. I just had a car accident and as I was driving I fell asleep and demolished my car. My doctor has given me PROVIGIL 200mg and it does NOTHING!!!!!!!!!!!!!!!!!!!!!!! There has to be some kind og a combination for sleep. The CPAP machine DID NOT MAKE ME SLEEP, in fact it kept me awake all night. I do have CHRONIC SLEEP DISORDER and I cannot understand why there isn't something for this. I was reading an article by DR MICHAEL RACK and he suggessted sleeping in a supine position and using a steroid nasal spray. He also suggessted on his website to use a SLEEP AONEA T-SHIRT. Is this approved by the FDA? If any one knows DR MICHAEL RACK'S EMAIL ADDRESS OR WHERE HE WORKS, I WOULD APPRECIATE. On the computer it says in is in JACKSON, MISSISSIPPI. If someone can help me find his address or email and if some doctor could answer these question, I would appreciate it. God bless you in your eforts!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
