This time around, so far so good! At least it is not constant all day long. I will have congestion to be cleared upon waking in the morning which is normal. Also after extended periods of immobility. But generally can open airway and rid the mucous after using Ventolin, postural drainage. So much better than before. Have at least maintained a higher O2 Sat so that I can increase my mobility. Even have started working out at the gym with a trainer. My lung fields have pretty much always been clear with no wheezing, rales etc. < its just been the problem with the bronchial secretions.
