@wangling I believe, I don't know for sure, it has been the air way clearance methods that has me clearing out the mucus plugs each session. In other words, all that one must do to help clear the mucus and mucus plugs. Exercise, eating well, good nights sleep, nebulizing, air way clearance techniques with the huff coughing. Again, I have BE with the MAI infection and have not taken the Big 3, so far. We are all different in terms of genes, attitude, where we live etc. etc.....so all that probably makes a difference Ling.
That's for your wishes of 'continue to do well.'
