Ya sure it's the flu? Check the lunar calendar.

I have a tried and true method (for adults only). Pour three fat fingers of bourbon. Slowly sip and then take a hot shower. Toss two or three extra blankets on the bed and settle in for a good nights rest. Your bedroom will stink like a distillery in the morning, but she'll feel a hundred times better. BTW, it works for colds too.
