Sorry you're battling nausea. I get that A LOT. I know they say carbonation is not good for IBS, BUT Gingerale seems to help me quite a bit when I'm feeling nauseous. I'm also an avid tea drinker for that. Ginger tea is gross (in my opinion) but it works wonders if you can choke it down. If not, Lemon Grass, Fennel, Chamomile and Mint teas work great for me too. You know, I've heard they make ginger gum... maybe if you could get your hands on a pack you could get through work tomorrow.
A few weeks ago I think I had a similar bug you had/have. I was super ill though... I had major D, a fever, lots of nausea, and I would have been puking had there been food in me. I sipped on tea and watery gatorade, and I managed to force down a few saltines. All you can do is rest and ride it out.
I hope you feel back to normal real soon...
