Goodness me. I just walked round to the corner shop and took some experimental deep breaths.
I have asthma and was thinking that it seemed much better. One of the ways you test the severity of asthma is use a little lung function meter; you take the deepest breath you can and blow into it as hard and fast as you can.
I could never use that thing without coughing. Never. And there was always a kind of rattly sound when I reached the end of the blow.
It's gone. Completely gone. I just blew out huge breaths really hard and fast and didn't cough once. No rattle. Did look a bit mad walking down the street doing this, but whatever ...
What a present for my one month anniversary. I know it sounds daft but it's given me a real boost.
