Thank you Sue! Very interesting, I do hope you continue to keep MAC at bay. I find aerobika hard to use, I get very tired. Am supposed to do 100 times a day, I only manage 30. Then I’m puffed and I feel vibration sensation in eyes, very weird. I use to be able to cough and huff up small amounts most afternoons. Since starting meds 2 months ago, nothing comes up. I was wondering if saline nebs might help. I also have bronchiectasis. The only time I cough copious amounts is when I have an infection of sorts. Anyway, thanks for sharing, I will have to persevere with airway clearance.
