@kjellis...Welcome to the group. Many others will have suggestions, but I know waiting for a response is difficult, so I'll tell you what I've been doing. My Bronciectasis is caused primarily by acid reflux. I sleep in an upright position and that has made a world of difference. I schedule all medical appointments from April through November, never in the winter. My husband picks up groceries and my monthly medications and the rest I order by mail. I don't allow grand children visits in winter. Thanksgiving is my holiday, and we make Christmas a flexible quick visit, so they are the only exceptions unless they are sick. We have a couple made-up holidays in spring and summer. I use hand sanitizer every time I leave the house and a mask if I have to wait in waiting room.
I also use nasal lavage every other day. These things have worked for me after the 14 month big three regimen and several bronchoscopies showed that MAC was absent.I take Dr. Tobias's Lung Meister daily plus Candida Cleanse after tests showed my lungs were full of it. I've been healthy since.
