@woot That post was over a year ago, I would now add while doing the postural drainage lye flat on your back with hips elevated (I use an under mattress wedge for my reflux issue, then lye backwards on the mattress so that my feet are 5" higher than my head). So in this position on my back I self percuss my chest, then roll over on my stomach and get wife to bang on my back. At this point I usually feel a lot of congestion in my upper trachea so I then roll back over and start my huff coughing as in my first post. A lot of detail here but it all works really well for me.
