What can I eat and drink to get rid of this small cold?

I have a small cold at the moment, it just got born!! barely, so I really believe I can get rid of it before it gets worse! what can I eat and drink to help get rid of it today?

So far I was thinking 2,000mg vitamin c
hot drinks, anything like tea or hot milk right?
elderberry (i have some)
thera flu syrup, not the drink.

and also other than eating, I am going to just rest today, no talking on the phone since I have somewhat a small soar throat, and I will try to let my body rest.
