I've had a Cpap machine for nearly 10 years now & I gotta tell you it is a better invention than sliced bread. You will sleep really well, no snoring, no snorting & when you wake you will feel like you had a good nights sleep.
The best part is that during the day you will not feel as drowsy & will not fall asleep as easily in meetings or while waiting for the lights to change.
I have sleep apnea & was starving my brain of oxygen while sleeping - it has definitely damaged my short term memory.
