Brian, I have a Bi-pap machine that I use, along with a "nasal pillows" mask. A bi-pap is very similar to a CPAP except that it delivers 2 different pressures, a stronger pressure for one for inhaling and a lighter one for exhaling.

I love my nasal pillows mask! It fits just into the nostrils, I know that must sound gross, but it allows me to read or do computer work while I am adjusting to the pressure.

I have to say a good nights sleep, although rare in my neck of the world due to other issues, is PRICELESS!

Good luck!
