@irenea8 it smells bad, but I've gotten used to it. And it did help to thin the mucus, but when had been on brinsupri for 4 months, the amount of mucus I was able to bring up, kept listening and listening. Now I am not bringing up any mucus, but my pulmonologist said, do not stop the airway clearance, keep trying, so she's going to add 7%. Sodium chloride to my nebulizing meds in hopes to thin the mucus, more.
