Aw, I'm so sorry for you!! I got food poisoning a few weeks ago (reheated porkchops) and I could barely eat anything for a week afterwards. I still haven't had pork again since it happened.
That's the worst thing, when you have nothing to sick up and your body insists on trying anyway, so you just keep sicking up that yellowy bile stuff....BLECK.
Drink lots of clear fluids and get some rest. Hope you recover soon!
