@rits This is great news! I haven't been on the site for awhile, but you're the first person I've heard of who reports clear having used the same protocol as me. I too am MAC free after 3 sputums tested within a 5 month period. I initially was on the Big 3 in 2018, stopped for a few months, then started again. Added Aricayce inhaled for 3 months. Eventually stopped the Rifampin, but remain on Azithromycin and Ethambutol. The one thing I hope to continue is nebulizing 7% saline as I have never had a problem with it. Especially now with Covid, I can't help but think its cleansing my lungs! Follow up w doc in a month and we'll see what's next med-wise. It is possible to convert to negative and I'm so pleased to hear your good news!
