@ckscoville I definitely wouldn't wait that long. I have atypical cystic fibrosis, MAC and bronchiectasis. My CF doc prescribed my vest and Dornase Alpha Pulmozyme inhalation solution for me after my last major exacerbation in 2018. I haven't had to be hospitalized since then. The Pulmozyme is expensive - over $4,000/month. I'm fortunate that my insurance and supplemental insurance covers it. Definitely something to ask about. Linda
