Hi Jessica, I was nauseated for a while after surgery but Im happy to report that its gone away for the most part. I had mine done on 12/21/10 and I rarely have nausea now. It does happen when I eat a little too much but other than that im alot better.
As for spitting, I didnt have that problem but I had a thick white film on my tongue for 6 weeks or so and bad breath and dry mouth as well. I still struggle with the dry mouth if Im not hydrated well.
Hope that helps.
