I've heard do not take any medication to fight the fever. Let it go as high as 103/4 then take tylenol to bring it down if needed.not advil or any others as they will allow the virus to take hold. Fever is what kills the virus in our bodies. Stay hydrated drink Gatorade with real sugar to give your body nutrients to keep the fever going . Better Gatorade than the iv they give you if you end up in hospital. Breathe deeply to help break up the phlegm and if it is bad use a extremely minty toothpaste and go in a hot shower with it breathing deeply to help loosen phlegm .
