What can I do to get healthy again?

I've been sick for the last week, and its horrible. I'm a college student, and I really dont have the time to be sick, while balancing a full load, work, and a social life. My roomates kids have rsv, and she's been sick also. I have a sore throat (even though my tonsils were pullin), a runny nose, a head ache, i'm tired, and I keep sneezing! Does anyone know any home remedies that I can do, that you know are proven to work? PLEASE PLEASE PLEASE HELP ME, I"M ONE SICK GIRL!!!
oh btw I get really sick from cold med's so i tend to stay away from them…. anything else?
