You need to do it all
Diet, exercise, airway clearance all help but if your MAC is progressing meds are needed
I took big 3 then added clofazimine but did not finally get rid of it until Arikayce added, which cleared up the last of the infection in six weeks. Still faithful with my airway clearance
Re hearing loss if it’s a problem in 10% remember 90% are ok
Get a good baseline hearing test and a vision test too
