I sure hope you get your new lungs soon. When I had heart failure I also had a 24/7 horrible, awful choking cough. It made me think how awful it must be to live with cystic fibrosis. When I got my heart transplant all that was gone, gone, gone. I hope the same for you.
I wish you WELL and able to enjoy a long healthy life. Holly (old enough to be your grandmother! )
