ok...think i'm crazy but...
chicken soup. (unless your vegetarian/vegan in which case i'll apologize in advance for this post)
I swear by it. Homemade if at all possible. Boil some chicken - you can add some powdered soup mix if you really hate making homemade, i find its a bit salty. Or even a chicken bouillion cube or two (again too many makes it salty). Boil that chicken till its falling off the bone. then take the bones out, leaving the meat in. add onion, carrots, celery.. whatever you have in the house. My dh adds rice and potatoes to his! i like matzah balls or noodles in mine. Theres something bout chicken soup that really really does help!
vicks under your nose and i second the vaporizor too. (we've been fighting colds/sinus infections for a while)
