Remember, too, David, that you're on a "get healthy" kick and when you lose weight, you may discover that you no longer have sleep apnea. That was the case w/a friend of mine who used a C-pap until she lost weight and now it's no longer necessary. Until then, the C-pap will help you sleep better and when you're rested, you'll have more energy to work out and get into shape. Good luck and sweet dreams.
