It may eventually help with breathlessness. If that is an issue and the saline doesn't help, you may want to ask your provider for either a "rescue inhaler" similar to albuterol to try, or a nebuliser solution of albuterol (the preferred solution for long-term use.) My daily personal assessment of breathing situation determines whether I start with levalbuterol, followed by saline, or just do the saline.

@rvan.rvan I would hope too. I used to be very breathless. I have never gone on the big 3. My path has been just 7% saline, correcting my Gerd, excercising very regularly and eating well and I now breathe like a champ. (Oh, and I also take NAC for my lungs) I was originally haphazardly diagnosed by my GP as having COPD but later a pulmonologist found MAC and Bronchiectas.... Shortness of breath had been a problem for several years prior to diagnosis but cleared pretty shortly after addressing the Gerd and really taking care of my general health with a good diet and excercise. I am hopeful that you will get there. Sorry this is a winded response...but it is hard to say any one thing was responsible. Kate
