zoomzoom, i think KillaKali dancing bananaman is right. It can be hard to understand how you convinced yourself that you need to throw up, but you can find a way to not throw up. I once did too much weed and I felt on the bridge of barfing for about half an hour, then I just started doing a bunch of math in my head because I somehow realised that would make the sickness go away.

Doesn't really make sense, but try just thinking yourself out of it.
