TweetSymptoms sound like classic "FOOD POISONING"
(ie, everything coming out of all orifices, totally wiped out due to massive dehyradtion, drink something comes back up)
Take a few aspirin, drink a few cokes, see if you can get your blood sugar level up and you should feel a tad better.
You will be shaky for a few days, yet, good to go in three.
Either way, CALL A DOCTOR, or get to one, best not to fool around.
Hope You Feel Better
