@imatcha I really think that in the past, before the importance of nebulizing saline, daily airway clearance and exercise, infections recurrent much more often.

But, many of us here have established routines that keep us healthy. I stopped antibiotics 58 months ago, and feel as healthy as I ever have in the past 8 years.
The gold standard will be my CT tomorrow and repeat Pulmonary function test (the last one was done while I was at the end of Covid.) Not sure if I will do a sputum culture as I am not very productive.

I would encourage you to use your neb a couple times a week with saline - there is coming to be more evidence that it helps. I do mine 2-3x week, and usually I exercise as my form of airway clearance. A brisk walk or 30 minutes of yoga bring up more mucus for me than any other technique.
