oral appliance for sleep apnea-anyone tried one?

I was just diagnosed with severe sleep apnea, two months after my sleep study was done, which was months after my initial consult. Now I'm booked for another sleep study to try out a CPAP machine, I think, but not until April. Must be nice to get fast attention to this problem.I have been complaining about being tired all the time for, oh, years. Ten years ago a sleep study supposedly showed nothing, and I was just as tired then. But my memory was better. Anyone have the experience of sleeping more poorly after experiencing whiplash?
I'm looking into an oral appliance to treat the apnea, although my specialist says my apnea is too severe. If it's that severe, why will it have taken me nine months to get the machine he thinks will solve the problem? Sorry, just whining. I requested the sleep study in the first place; my doc was convinced that antidepressants and excercise would solve the problem.

I think it probably has a lot to do with who is paying. That is probably why it is slowed down.
If you were paying, it would happen quick.
I belong to a HMO, in Michigan, and had to see a specialist for another problem, and she recommended to my primary care doctor that I have the test.
Once he said OK, I had the test, (never saw a sleep-doctor) and the results were sent to him.
He didn't know what to do with them, so he sent me to a pulmonologist (another week) who then had me on a machine the next day.
Since then, I have been dealing with the pulmonologist.
Note! If you are doing the paying, shop around for the machine and gear. Much, Much cheaper on the internet.
My first machine, insurance company paid 1300, for a 535 machine. Could have been bought used on EBay for 25. Just a word of warning, watch your pocketbook.

I just can't believe that it will take you until April to get your machine.There must be something holding up the process.
I had the sleep study done, and 2 days later had the machine and all of the equipment.And I don't live in a big town.
You need to do something about that.Call your Dr. or call the company that will supply it,and they have a respiratory therapist there to help you.
I am also finding out so many new things since I have joined this forum.
Hope you get your machine soon.

Helen,
I have a TAPS (Thornton Adjustable Positioner) http://amisleep.com/home.html
and although it does set my lower jaw into a more forward position, it doesn't take care of the sleep apnea. I also have severe apnea. The device does help me keep my mouth closed, but it cost about 500.00 and I'm not sure it was worth it. But since I grind my teeth and also have jaw problems it has helped, as I needed to wear something and this device does stay in my mouth all night, unlike other mouthguards I had used.
Good luck,
tk

My dentist said he read about a device. He is going to back to me on it. Like that will happen
