I ate half a new york steak sandwich that was left out for ten hours i made myself throw up as much as i can is there anything else i can do?

Decision making: You do not have to make yourself throw up as spoiled food will cause that naturally most of the times. The most important piece of information missing here is what were your actual symptoms and what are you left with. Other than staying hydrated and trying to avoid eating spoiled food in the future there is not much else I can recommend. Most importantly do not make yourself throw up.
