Do you ever wish you could throw up on command?

Some days you just feel queasy. Not sick, just yuck. You stomach is at odds with you and you don't know why. It is frustrating. You wish you could just hurl, but you can't.
I think our bodies should be equipped with a "yak at will" reflex. I mean, come on stomach, I have stuff to do today. Just get it over with so I can brush my teeth and get on with my errands. We don't have time for nausea.
It would also be great if our bodies would expell all the junk at once when we blow our noses.
