Hi ScoopThank you for taking the time to respond. I will definitely check out her book! Is it on Amazon? As for my AC since I always have a lot of mucus, I don’t even need reminding of airway clearance at least twice a day, sometimes three and I absolutely hate it, and I will be doing it the rest of my life! (As y’all know) I use 10% solution, others use three or seven %.) I use a massager, Aerobika and physiotherapy techniques. I tried the vest and didn’t find it very helpful. I do find if I don’t move my body I feel worse. It’s hard sometimes but I force myself. Let me know about the book. 😊
