Anyone sleep with CPAP therapy?

I told my general doctor that I was often tired in the morning, so his first test was for me to wear a finger device that measures oxygen levels in the blood. This was "prescribed" and I was given this device to wear overnight and it continuously measured oxygen levels. The device did show that during the night my levels got down to 83 - which is a problem. I was waking up every morning at about 4:00 a.m. My nose has always had some blockage, and I am a mouth breather.

So the next step was to have that sleepover at the lab: all hooked up. This is an expensive procedure and insurance companies don't want to pay for it, but mine did. My S.A. doctor said that even plain snoring is a sleep disorder.

Anyway, a CPAP machine and mask was prescribed and I use it every night. The mask was hard to get used to at first (which is pretty common). I now sleep through the whole night. I swear by it, not at it.
