Yay! I've finally managed to sleep the entire night with the CPAP machine. Not only that, but I've done it three nights running. I do still wake up in the middle of the night, but I can get back to sleep afterwards. So far I haven't noticed any real improvement in how I feel during the day, but that's supposed to take two weeks or so of solid use to start to notice a difference. At any rate, it's a tremendous load off my mind since up 'til now the choice seemed to be between surgery that had at best a 50% success rate (and that my insurance didn't want to pay for) and an early death. So even if I don't ever feel like leaping out of bed in the morning and running a marathon, I'll be pretty satisfied.
