Hi bayarea. You're right about people being treated successfully then not checking back in to the MAC groups. Happened to me. I was so happy to be done with 3 solid years of treatment that I was like "I'm outta here and never want to come back!" I think I started the Mac horror show in 2016. The big 3 didn't seem to work. I was jamming those monsters down my throat for two solid years and still.... mac mac mac. So Arikayce was added to the mix. Another year went by where I was taking the big 3 and arikayce with it. I probably didn't even need those 3 dumb meds. It was the arikayce that did the trick. Anyway by the time I endured 3 years of treatment --- and when I finally got 6 months of negative cultures back I was sick to death of the whole routine so I decided to never go back to a doctor again. I'm done I don't care to even know if there's mac in there. Doesn't seem like it to me. I live alone on a little homestead in the country and I work like a 35 year old man. (I'm 71) When I'm chopping wood or cutting and stacking a field of hay with hand tools I think to myself . "I'm cured." My mind says I'm cured and I believe it.
