Scoop-
Did somewhat of a 'deep dive' after your post and looking up Buteykoclinic....in Ireland.
From there the following named techniques: diaphragmatic breathing, purse lip breathing, 4- 7- 8 breathing, box breathing and further we have Active Cycle Breathing, Autogenic Breathing.....
Happy breathing to us all. Hopefully lots of good results for us with the all important breathing techniques for everyone, and especially us living with BE.

Thank you! I have mild asthma so definitely interested in reading. In fact, I can never tell is my cough from asthma or MAC? Definitely, prolonged the diagnosis.
