How do I keep my fever? I got to stay home but I'm going to the hospital later and I wanna keep my fever?
Well, why would you want keep a fever, you know what seriousness that can do to you? You should consult a medical doctor and tell them your symptoms but you should seek professional counseling (no offence).
You shouldn't keep a fever if a fever reaches levels as high as 101 degrees and higher your brain can start to die due to the temp. If You have an fever you might have an infection, a fever developed to help fight off infection but if it prolonged it can cause serious help issues. I seriously recommend that you end the fever and concsult with your doctor
