If i ate some bad food and need to throw up right away, what do i do or take?

Throw up first.: If you need to throw up, go to your bathroom and do it. This is the body's way of removing bad food, etc., so you don't get real sick. If you cannot , get some mom (milk of magnesia) or syrup of ipecac to help induce vomiting. After that, have simple inert foods, like bread and drink water for a while. If you have fever, etc. With this, it should go away, if not in 24 hours, see dr./er for rx.
