My wife has a slight fever and some chills and wants to know if she should use Tylenol, Advil, or nothing? Should she rely on drinking fluids, restrict her food intake or what else she should do to help the symptoms. She was recently exposed to her grandchildren who have all had colds, and two had a stomach/vomiting thing, along with hundreds of kids in the KC area, apparently. My wife is not nauseous at this time.
