I check into the bronchiectasis MAC chatrooms infrequently - delighted! to see this today 5/17/21. Been using NAC quite awhile, NAC Sustain not as many months, but also been using Colloidal Silver & herbs like Pau D'Arco, Herb Pharm Lung Expectorant, Olive Leaf extract (caps) as well as Proteolytic Enzymes (along with my regular menu of basic supplements) - so can't tell EXACTLY what's made me so much better in last couple years; probably into overkill & too much expenditure. 🙂 Have had bronchiectasis 26 years, MAC about 7 - didn't show up on my last sputum test! Wish I could restore more of my energy, but been so much better past 3 years, can't complain. & haven't had any antibiotics or other drugs in all that time either. Turned away when told by pulmonologists at point of heavy sweats nightly, frequent shortness of breath & loss of almost 20 lbs. that the only thing I could do then was take "the cocktail" of 3 strong antibiotics for the 18-24 months with no assurance of much or more than MAYBE couple months' success. To say nothing of the potential side effects I might've experienced. I think it important whenever possible to think outside of the box/dominant narrative. Blessings all & keep positive!
