Can anyone tell me if they have such trouble trying to shift very sticky mucus that the airways seem to fill with it & no breath seems to get through causing extreme panic. If so please tell me how to cope with this as I am living in fear of it happening whenever I have to cough. I take 2 mucodyn caps 3xdaily also have saline nebs& a flutter device. I have stage 4 emphysema with bronchiectusis & my fev 1 no is 26%. Hope someone can offer some advise as I've had a really bad day of it. Thanks in anticipation.
