my favorite fight-off-a-cold remedies:

hot water with lemon juice and honey

zinc tablets that you dissolve slowly on your tongue

Yin Chiao, available at Chinese health food stores (make sure it contains forsythia: http://www.yinchiao.com/yinchiao.htm)

Ganmaoling, also available at Chinese stores – take either this or Yin Chiao, not both

hot tea of any kind

sleep

hope you feel better soon!
