Sue and Spencersok, I have been using a nebulizer two times a day and it really helps in getting mucus out. Especially before going to sleep. No longer cough at nite. I have Bronchiectasis and MAC. Its my understanding that the treatment for MAC is difficult and can lead to other ailments. So am I correct in thinking that what I am doing is to get rid of mucus and infections from the lungs? So far my Dr. hasn't given me any medications for MAC but to clear the lungs with a saline solution. Hauoli
