I have been using my CPAP machine for about 2 months now. I was diagnosed with moderate sleep apnea, waking up about 30 times an hour. I've noticed that since I started using the CPAP, I seem to wake up after 3-4 hours and feel wide awake. I then have trouble falling back to sleep. Is this typical? I suppose since I'm getting better sleep, my brain thinks it is time to wake up? Thanks.
