Ugh, hope you feel better soon.

When I'm sick, I like to drink those smoothies from Naked or Odwalla that you can get in the grocery store. I'm a fan of Naked's Mango Tango and Odwalla's Mo Beta. But there are other good ones too.

Also, if you have a sore throat Traditional Medicinals Throat Coat tea works pretty well (they have it at most grocery stores).

Zinc supplements, too.
