I am doing ok on the frustration level for the most part. The main stressor comes with making sure I can still work to take care of my wife (she has early onset Alzheimers). I am ok with slowing down as well but I am hoping that the doctors can improve my breathing a little. As far as coughing goes, I'm on a pretty constant prednisone regiment so I don't cough much. When I'm not on prednisone, I cough alot, alot of mucous, and frequent bronchitis (which takes 4 to 6 weeks to get rid of).
