Take a look at what many of our members have to say about staying healthy after the antibiotics. There is no one-size-fits-all plan, and we need to find our own path.
For example, my bronchiectasis is stable, my infections held at bay for almost 4 years by 7% saline nebs, but no longer daily, with daily airway clearance. I do not boil my water, nor worry about showers, but I am cautious about soil contact, wearing a mask when I garden in dry soil. I have others handle my digging & mulching to minimize exposure. I swim in the ocean and outdoor salt water pools, but not indoor pools. I don't go neat hot tubs.
