Throwing up after wisdom teeth removal?

I had all four of my wisdom teeth removed today.. I was put under general anestesia and also had laughing gas. It has been about 12 hours since then and I've been having a lot of nausea. My question is in case I throw up how do I clean it up? The sheet of care I have says only to rinse on the 2nd day, but it also says I might throw up on the first? Has anybody else had to deal with this? I stopped taking my hydrocodone or whatever and my nausea seems to be getting better. Thanks
