It is true. Sleep apnea can effect your overall health. You can get heart problems and high blood pressure. You may notice tiredness during the day. ....I have been on c-pap for a while. Suddenly , I started waking up with my mask in the floor! My machine is even off. I am throwing my mask in the floor and turning off the machine in my SLEEP! that is so weird. I don't know what to do, but I am trying to keep it on all night.
