@haiku I too find all the coughing embarrassing That plus fatigue keeps me away for many social interactions. I hate the mucus, most especially when I get into bed, longing to sleep and I start coughing. I have to get up and bend over to help drain the mucus, sometimes 2or3 times. This happens most nights and takes the pleasure out of going to bed.I nebulizer twice a day, helps some. My cat scan regularly show very little progression of the MAC...I guess it's the bronchiectasis, in part that is causing the coughing. No body seems to really know..
