Jim, sounds like you're doing great, being released so early and all! Hey, I know what you mean about that breathing thing, but don't get discouraged. I couldn't get it above 1000 for the first couple days, but by the 3rd and 4th day I was getting it up to 1500 and it got better almost every day thereafter. Was up to about 4000 last time I checked. Those lungs will come back - just give 'em time. And don't skimp on those breathing exercises - they're important. And so is the walking! Let us know how you're doing when you get home!
