@ursala7 Laying back is the only way I can consistently get out much mucus. Here lately I've been having to over-extend my recliner and tilt my head toward the floor to get much out. I'm wondering if the vest is somehow just packing the mucus in. Anyway, I can get about 6-8 blobs out in 30 minutes. Their sizes range from dime sized to maybe half dollar sized but most of them are quarter sized. I feel like I'm working about 50% harder now than when I started all of this, and getting out far less mucus. When I first started all this airway clearance I was getting about 10 huge blobs out within my 30 minutes.
