Oooh, Oooh just remembered another one, when I am in sore throat stage, I find eating garlic, in my case bread covered in garlic, seems to fight the bug. I find Neo Citran works as well, but instead of putting vodka in it, I have 2 servings. Then sleep. I have avoided colds this way in the past, if you don't have time to sleep then you may be out of luck, but you might be ok by Friday.
