Get some Gan Mao Ling. It's a Chinese herbal formula that helps ward off colds. You can get it through an acupuncturist, or you can get it online. You might also find it at Whole Foods or other places where you can get natural remedies or herbs. Start taking the pills at the first sign of a cold or flu-like symptoms, and take it for a couple of days. You can also do a mechanical "release the exterior." Fill a tub with water as hot as you can stand. put in a tablespoon each of powdered ginger and cinnamon. Sit in the tub until you definitely feel warm, then get out, dry off, and wrap in a blanket and drink something warm--- cocoa, coffee, hot tea, or, even better, ginger and/or cinnamon tea (chai tea works, too!). Stay wrapped up until you break a sweat. Avoid getting chilled, and your done. Don't laugh--- it really works. In Chinese Medicine theory, the sweating pushes the "evil" out. (Basically, expels the virus.)
