Yeah... what're ya gonna do? DH finally ended up with the CPAP machine because of a series of unignorable health problems. It was an attempt to treat a-fib that left him exhausted—which started prior to (possibly resulting from) a diagnosis of a fairly rare bone cancer. All treated (actually CURED) now (which is SO rare in the medical field). I don't often walk with him any longer because I can't keep up without hurting my right hip joint. Used to be he had to walk slowly and stop often. Now he has apparently lost the ability to walk (what he calls) slowly.

I blame the dam CPAP for that, but at least he doesn't keep me awake with constant snoring & gasping.
The CPAP was not successful at normalizing the heart rhythm, but he feels so much better it's absolutely unreal. Also (completely unexpected) he sleeps all night now. He thought it was his prostate waking him, but apparently it was the anoxia waking him and the wakefulness sent him stumbling to the bathroom. I'm sold on the CPAP. It's made a huge difference in his life.
