Hi @aerogirl, I'll add my welcome. While you might be new to Mayo Clinic Connect, I see that you are not new to MAC and Bronchiectesis. This forum was started in 2011 and remains very active to today. You can see the origins of the group and meet most of the members in this discussion
– (MAC/MAI) MYCOBACTERIUM AVIUM COMPLEX PULMONARY DISEASE/BRONCHIECTASIS https://connect.mayoclinic.org/discussion/mycobacterium-avium-complex-pulmonary-disease-macmai/

As you browse the topics of the MAC group (https://connect.mayoclinic.org/group/mac-bronchiectasis/), I'm confident you'll see your experience with anitbiotics, aerobika, 7% saline, silent reflux, etc echoed by several members. What I know you'll find is a supportive and wel-informed group of people willing to share their experiences to learn, support and discover. Glad to add you to the group.
