I agree with sweating it out. That's what my family did years ago and it still works for me. I listen to my body. If I have the chills, I pile on the blankets, hot soup and herb tea, and plenty of room temp water. I do this until the fever breaks with the sweats and feeling hot instead of chills. A shower or bath, plenty of rest and fluids follows. A fever is the body's way of speeding up metabolism and putting the immune system into high gear. I'm not advising anyone on how to treat illness but this is what works for me.
