Sorry to hear that Gayla. I've never found anything better than lots of rest and hydration.
I also supplement with vitamin C, a multi, and ZMA when I'm sick...all of which help boost the immune system.
Here's a good article dealing with this issue:

The only thing I disagree with in this article is eating high protein (1-1.5g/lb lean body mass). I'm sure this is good for you, but when I'm sick my body can't handle a big steak, or chicken breast for that matter. Even protein powder has a hard time going down. So I usually make a big stew or soup in the crock pot and dip into that several times a day.
