It’s great that you’re so active. Exercise helps a lot, too. I’m just finishing nebulizing the saline and will walk/run just after as airway clearance. Members who expel a lot often do both. I don’t get stuff up, but started regularly using the 7% last fall. My pulmonologist suggested it in hope I’d have fewer exacerbations over winter and it seemed to work. Last month, he said it was like flossing-good prevention.
