This disease forced me into disability at 62. Fortunately the long term disability along with Social security disability made it easier financially, but it meant that there was a lot that I could no longer do. Moved to Tennessee 5 years ago because we found out that I could breathe better here. I was started on O2 nine years ago. 2 liters when I am sleeping. That hasn't changed. Blessings to everyone!! Breathe easy
