I am one of those people who seems to catch every cold that's going around, twice. It doesn't help that I'm a teacher and have a five-year-old. Right now it's extra obnoxious because I'm always worried I have the big C and have to wait for a test. It may just be a crappy immune system, but I'm wondering what you all do that seems to help prevent illness or at least shorten its duration. No idea is too basic (wash your hands) or too out there (neti pot? idk). Thank you!
