I tracked down a breathing specialist and after 1 session my “air hunger” which is exactly as you have described, began to sharply decrease. Now, just 5 days into my breathing exercises, it’s nearly gone. This is after about 4 years of suffering. My son who has it way worse than I had is scheduled for next month. This guy is the real thing. Read his credentials. I am grateful to have found him. His name is Ciaran McKeown at breathamy.com. Please note that he is not the one that created the breathing method that he teaches, but he did use it to solve his own problem, exactly like ours, plus his asthma. This breath technique that he teaches is absolutely life-changing, and very easy to learn.
