Ellen:
The new "Normal" will continue to improve.  It's strange really, I was told two years out would be about as good as it gets, however I still feel improvements.  My surgeon said it's also adaptability, what we don't get back we can "Adapt" to.  I probably don't stay hydrated enough but I don't always have a water bottle with me any longer either.  Advice; stay positive, experiment (As things constantly change), continue to keep an open mind, learn, grow, laugh, love!  We're breathing!
Warm Regards,
Steve
