Take a deep breath - as deep as you can. Then suck in more air. Keep sucking in more and more, kind of like a fish does when landed, and keep sucking in air until you can’t any longer, then hold it as long as you can. If it doesn’t work the first time, exhale and repeat. Guaranteed cure, as it stretches out your diaphragm and releaves the spasm.
I await my Nobel Prize.
