My wife tried to get me sick last week. She works in an office where lots of people don't think they can take time off when sick, so they show up half dead and spread it around.
She went down for the count on Sunday with a fever, cough, and generally feeling poor, and still had the fever yesterday when I talked to her (I had to get on a plane).
I started to get the sore muscles and general drained feeling, but I managed to kick it with Vitamin C, Thieves Oil, Zinc, and Garlic. Yes, garlic. Take a clove of fresh garlic, peel it, chop it into swallowable pieces, and take like a vitamin. It'll kick the crud pretty effectively.
