Which machine is he now using? AN ASV? His sleep times are the same as what mine were. My husband use to wake me enough before he left for work to get me to take a Provigil. I do not have CSA however, I have a rare form of Narcolepsy along with OSA, Parasomnias, Automatic Behavior, Sleep Drunkenness, Myoclonic jerks.
Does he have any other known health issues? How is his B12 levels? Do you feel there is any depression adding to this?......very easy to be depressed about life at this age, unable to do much, feeling less of a man...shoot hard at any age when you just don't have the energy to roll over let alone get up and get going. How is his caffeine intake, alcohol, BP etc. SO many things can add to all this.
