Hi. I am wondering if most of those with Bronchiectasis (but not necessarily NTM/MAC) use saline twice a day, or sometimes just once? I am slowly (slowly!) building up a tolerance to the 3% and only once a day so far. I have both asthma and VCD (vocal cord dysfunction) so am very "twitchy" in my airways. I have found using the Aerobika at the same time as the nebulized saline helps, but it also really tires me so not sure I can go to twice a day!
