Yes, I did for 18 months due to the severity of my infection. After learning on Mayo Connect about airway clearance, and eventually 7% saline, I asked to stop due to feeling worn out from treatment, even though I still had positive cultures. That was 3 1/2 years ago, and with continued prevention practices, I am still okay. Won't know how my lungs look until my next CT in December.

I'm pretty sure, as sick as I was, that the drugs were vital for me. But every case is different, and if mine was mild, I would plead my case for "watch & wait" with daily airway clearance, periodic sputum testing and CTs.
