Yeah my day has a C-PAP and I've seen the difference. I do realize the effects span more than waking up every now and then in an absence of breathe, cause I do feel the fatigue and aches and pains. I just don't know if at my age its such a big deal.If you are waking up not being able to breathe please go see a doctor. I have sleep apnea myself and am on a C-PAP machine. The machine can make a whole world of difference for ou, it can be life changing. Sleep apnea can affect you more then you would think.
