I, too, had to stop because of side effects from the azithromycin. That was my second go around with the Big 3 and it didn’t work. I quit in November 2022 and my last CT in August was unchanged. I still use albuterol everyday just to keep my lungs open. I walk, I use a dry salt inhaler (Nevelers on Amazon) and I see my acupuncturist and integrative medical doctor. I have decided that I will enjoy my life without those meds and explore other avenues of health. I also have since discovered (thanks to my integrative doctor) that I have IgG, and IgM deficiency and would have never been healed by the Big 3 until I remedied that. I now see an immunologist. Someone on here wrote that MAC is different for everyone and I also believe that the healing with it is, as well. I wish you all the best! Carolyn
