Yea, I guess I should just be on top of washing my hands and being careful with things. It's just annoying living in a house with a bunch of people who I don't think are the cleanest and it worries me about what germs they're bringing home. I have heard of peppermint and I've chewed gum a few times when my stomach is upset. I just heard about this oregano oil while I was researching but it seems to only be available online. Thanks for your help!
