I wrote that question in 2019. I stopped taking the meds a few months after starting when I went to Mayo. My Dr told me at Mayo that the antibiotics big 3 should never be subscribed unless you are really bad whuch I was not. He put me on neb treatment. I just went back yesterday and my lungs were almost clear and no sign of Mac. All tests came back negative. I have worked through covid, no longer wear a mask and love yard work and never wear a mask. The key is keeping the lungs clean.
