In answer to Aida's question of how I'm working to keep from getting MAC again:
1) diligent airway clearance, with 7% saline twice a day, using an Afflovest once a day
2) purifying my drinking water in a LifeStraw pitcher
3) wearing an N95 mask when outside gardening
4) taking short showers with the bathroom vent on with shower door and bathroom doors open
5) using GERD precautions (since I have GERD) like sleeping with my head elevated 30 degrees and not eating or drinking for 3 hours before bed
6) minimizing stress , exercising and eating well to keep my immune system strong

I don't know what else I can do, because NTM is everywhere in the environment and I'll most likely find it in my lungs again, but we can only do what we can do. God bless!
