O have a flu, what's the best way to end it?

Prevention : The best medication i know of for influenza, if taken very early in the course of the illness is tamiflu, (oseltamivir) but at best it may improve your symptoms and make you feel better faster. Truly, influenza generally has to run its course. Best way to end it, is to get annual flu vaccines and during flu season (and all year long really) engage in good hand washing/disease prevention strategy.

Flu: If you have the flu hydrate well w water, herbal teas, soup or juice. Drink sufficiently to have pale to light yellow urine. You can use pain relievers like tylenol (acetaminophen) or nsaid’s. Rest a lot! in some situations antiviral medications (tamiflu, relenza, flumadine) may be prescribed within the first couple of days of symptoms to hasten healing or they can be used after flu exposure to prevent illness.
