I'm going to personally warn everyone.......this stuff sucks. I've been sick since mid Friday. Finally got to doctor Monday and was confimred that it was the flu. Only one other time have I felt so bad. So if you can, get the flu shot and stay away from sick people. I know that's very tough for us. The doctor even asked me, "have you come in contact with anyone with the flu?" I told her, "I'm a UPS driver, I come in contact with A LOT of people." And my daughter has been sick the whole time too and her doctor has instructed her to stay home all week from school. She's not happy about it. But she can't go to school and get others sick too.
