I think i have some temperature because of my stomach.i probably ate some bad food now i'm feeling a little sick.maybe coca-cola will help me?

Not good idea: Coca cola is toxic with huge amounts of high fructose corn syrup that will cause a spike in insulin and cause inflammation & is also highly acidic. It is best avoided at all times, esp. if ill. You might try Ginger tea, the homeopathic remedy Nux vomica, and Chinese "Curing pills," and/or charcoal capsules all available at health food stores. Drink lots of fluids. Symptoms should pass soon.
