I just went through a sleep study and was diagnosed with obstructive sleep apnea. My sleep was being disturbed 69 times per hour. My doctor has prescribed a CPAP (Continuous Positive Air Pressure) machine, where you wear a mask to bed at night and the machine blows air down your throat. He prescribed a type that automatically adjusts the pressure throughout the night. I should get it within the next couple of weeks. My only experience with this CPAP machine was during the second half of the sleep study, for about 3.5 hours. Does anyone here use one? Does it help? Any advice or tricks of the trade in using one? Thanks a lot.
