@scottbliz I concur! This Mayo chat was very helpful for me both before and after my procedure. I got a lot of encouragement when I was nervous or having issues (like my post surgery pericarditis), etc.
One thing that I found helpful was to keep exercising despite being tired... just do a bunch of shorter bursts of walking, rest a bit and do it again. That should help both your legs and your breathing. ...and be sure to use that incentive spirometer they gave you in the hospital (I still use mine from time to time). If you don't have one, get one as it will help your breathing. Good luck!

@scottbliz How is your recovery coming along, Scott? With luck, by this time, you are out doing most things but don't despair if it takes longer.
