I'm relatively stable and I nebulize twice a day everyday to keep airways as clear as possible and to reduce the likelihood of NTM, pseudomonas, etc. Even though my bronchiectasis is mild, with increasing age and loss of lung elasticity, it seems the phlegm accumulates more than it did when I was younger. I feel better after airway clearance especially in the morning. P.M. I have to make myself do it. When I'm brewing something I increase the nebbing to 3x-4x.
