I think the low hanging fruit has been plucked when it comes to your lung progress. We're back to the long slog. No more giant leaps. Your mother and I were a little depressed when you backslid over the weekend, but you seem to accept sleeping on your back now so I suppose it was worth it. You are beginning to regain your ground, one or two points at a time. The good news is that its unlikely you'll face as many "catastrophic setbacks" due to infection now that you are bigger and the endotracheal tube is out. I'm fine with a long journey from here on out, so long as it is a pleasant one.
