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!
