Sooo....I work in a very small office. It's a 400 sq. ft. glass box. And one particular co-worker has come in sick. ::sigh::
I was sick all last holiday season. I REALLY don't want to be sick this year!! REALLY, REALLY, DON'T WANT!

So I'm trying to do everything I can not to get sick.
I'm using airborne:

EmergenC (in which my other co-worker just informed me that it does NOT have the new improved flavor it brags about):

Echinecia:
And even black elderberry:

What else can I do?
Do I already have my bases covered?
I already have a scratchy throat.

I'm trying really hard to not let it progress.
So what are your cold/flu season tricks?
