Sorry your sick but being back in warm Florida ought to help out. I am sick too from Thanksgiving visits and the dry air here is not helping so I got a humidifier.

I pretty much OD on vitamin c and that really helps a lot - vitamin c crystals dissolved in water. If I do this regularly I don't get sick. I should have known better with people gathering for holidays and the cold weather but I was too lazy. (Lots of Florida orange juice will help too )

Airborne, Zicam, Cold-eeze, and excess vitamin c are all pretty much based on the same idea and they do work and are great to prevent colds. They still help if you already have a cold but if all you want is something to help you sleep - Nyquil!
