I am starting to show symptoms of H1N1 flu, is there anything I can do to avoid the symptoms getting any worse?

I have a headache, a sore throat, a semi-stuffy nose, and my upper body aches. My family has had swine flu within the last week. I do not want my symptoms to get any worse because I do not want to miss school. I have been drinking normal amounts of water. What else can I do?
