Hi thumperguy, thanks for the compliment on my compliance but I too take random, very short breaks when I can’t muster motivation😔. I could not bring up any mucus prior to using the vest but had a pretty consistent dry cough. The combination of nebulizing and the vest tend to bring up the mucus for me and then sometimes for a little while afterwards. Periodically, during the day I still have my dry cough and rarely some spitting. That’s how it goes for me anyway. Wishing a Happy Thanksgiving everyone!
