Pale Yellow Stools, Vomiting, Dark Yellow Urine?

Well, from the sounds of it, it sounds like your body is still readjusting back to normal from the food poisoning bout. After all that vomiting and what not, you've become severely dehydrated. It will take a few days of fluids and electrolytes back in your system for everything to balance out again. I would fare to say that you should be fine in a few days, but if the symptoms persist or get worse, go see your doctor.
