Swine Flu?

I just haven't been able to recover since I got back. When I was in Dubai I was sleeping 4 hours a night and I felt great. Back home I've been sleeping 12 hours a night and feel horrible. I had a sore throat, stuffy nose, fever, and my stomach didn't feel great. I was hoping it would go away, but instead it's gotten worse. Today I had to leave work because I was so sick to my stomach. I've managed about 6 saltines and a few sips of water. And the marathon is 3 days away...... And of course this swine flu epidemic is making me nervous. I'm sure I don't have it, but I was a lot of airplanes and in a lot of strange places.
