@rmoore901 @gagaka I'm certainly in the dry BE group! I was diagnosed in 11/24, but have only been able to produce one sample at the beginning. Later, I had to have a bronchoscopy before starting on the big 3 in 8/25, due to progression shown on CT scan. Since 11/24, I've been nebulizing twice a day with 9% solution and albuterol, do ACTs, exercise, and still unable to produce sputum. I seldom cough. I also did two sessions in the doctor's office with no result. Frustrating because I don't want to do another bronchoscopy because of the risks (but the procedure itself was fine). But I keep up with everything to keep mucus loose and moving, somehow. I'm tolerating the big 3 just fine, with probiotics, and haven't had any flareups. We'll see where I am after 12 or 18 months on the big 3 and CT scan.
