You may already do this but are you drinking enough water and is the water that you drink warm water....not scalding hot etc. Sad to say my local pulmonologist, when I was first diagnosed, implied water doesn't help....shameful....and one of the reasons I took myself to NJH.
Paxmundi on this "blog" finds the warm water helps a great deal and I do also. Warmth, in general, loosens things including the mucus. I put a touch of honey in my warm water a couple of times during the day. It does seem to help... much of the time after doing that I bring up mucus/mucus plugs......and that often happen a good while after my nebulizing.
