This is a site I like a lot-- https://bronchiectasis.com.au/physiotherapy

In general, I take NAC and a long acting mucinex tablet with a glass of water. Then, I nebulize with levabulterol .63% and then nebulize 7% saline. Some people prefer to take 2 puffs of albuterol instead of nebbing levalbuterol. For clearance, I use the free autogenic drainage app (AD app) available on iPhone or Android stores but does not work with Sprint. It's like a breathing and huff cough coach.

Ask away. You're in good company. Plus, there's a ton of useful information in this forum, which can easily be searched on the MAC Bronchiectasis main page.
