There is a Facebook support group called Lung Matters: Covid, Bronchiectasis, MAC, NTM, Nocardia, Pseudomonoas and More. They offer a lot of advice on how to do Airway Clearance Techniques (ACTs) to keep our lungs clear, mostly nebulizing with Saline and Albuterol, and taking other precautions. I just finished 2.5 years of antibiotics and I've been infection-free 6 months so far and intend to keep it that way.
