What Causes Nausea, Vomiting, White Stool And Burning Feeling In Throat?

I had a strange event two days ago. I suddenly got nausea after feeling fine that morning, then vomited every 10 min for 2 hrs. The last vomit was dark green (like bile) after just light colored stomach acid (that burned my throat) for several trips prior to that. No fever, in fact my temperature dropped to 96.5 deg F, then back to normal afterwards. My stool has been almost white since, for the past 2 days, but otherwise normal, just low energy. That s what concerns me. Is this pancreas, liver or gallbladder related? Mike
