How to get a high fever overnight ? (idk, cause i see a lot people eat toothpaste to get one,but i think it's too dangerous)(yes, it's get, not treat)

Eating toothpaste: Eating toothpaste may give you an upset stomach and cause you to throw up, but will not cause a high fever. Anything you intentionally do to give you a high fever is "to dangerous". Don't try it!

Do not eat: toothpaste. It will make you sick to your stomach and not give you a fever. Why would you want to give yourself a fever. Doing so is dangerous.
