Green tea with some honey and a few tablespoons of apple cider vinegar(if you can stand it?). Lots of water and don't forget to eat. Don't eat anything cold if you can help it.
Apple cider vinegar (particularly Bragg Brand) is miracle product. Put a small amount in a cup with about 1/4c of water and just shoot it, and you don't really have to worry about the taste too much.
Rest! If I feel like I'm getting sick I generally sleep for about 15 hours, and sickness doesn't have an effin' chance.
