Colds - Tangerines all the way . Other fruits with Vitacmin C like apples and oranges help, but Tangerines are my favourite (besides grapes...), and they're also quite small, so you can always take a few with you if you're out and about.

Tea helps a lot, best to start drinking it as soon as you can instead of waiting for it to cool, but of course, try not to burn your mouth =P. Carry tissues around a lot, too, in case you have the sniffles...

And some pain killers. .

Coughs - I try not to talk as much as I can, and again, tea, tangerines... yadda yadda yadda. Wrap up warm... same applies for colds.


Technically, none of this works for me because I still end up ill for four months. >.>
