I cannot speak to the inhaled Arikayce. There are a bunch of posts here in this forum that can be easily searched about peoples' experiences with Arikayce.

For bronchiectasis, I've switched to using an albuterol puffer before 7% saline and airway clearance instead of nebbing levalbuterol, the later made me ironically wheezy. The puffer helps my asthma a lot so I carry it around with me when I will be away from home for the several hours etc.
