Hi, not posted for a while since my wife passed away after a long struggle with Pulmonary Fibrosis. Unfortunately her brother has just been diagnosed with Pulmonary Fibrosis and Bronchiecstasis (Sorry if I spelled that wrong. He's having problems with lots of mucus in the lungs just now and I'd like to ask if anyone has tried Autogenic Drainage to clear it? And if so how did you learn the techniques? Many thanks to all for your support during my wife's illness.
