It's a "vurp" if I remember the word.

And yep it's so quick and does not have nausea it's a non issue for me most of the time.

It bothers me if it's "white hot" and I don't have anything to drink to rinse the acid back down where it belongs. Every once in a while I get a hot one. Usually from bending in the wrong position and burping. It makes me envision boiling hot fire in my throat.

Thankfully that is a very very rare occurence.

Ciao!
