My g/f and I have had the flu pretty badly.
She started on Saturday night; I started Monday morning. I literally layed around her place all day yesterday, with severe swings from hot to cold, fever that came and went, bad headache, and stomache pains that came and went (only threw up once). Her's was about the same.
I called off Monday and Tuesday, and have today and tomorrow off. Even though I slept a bunch yesterday, I've been sleeping like crazy today. Went to bed before midnight, and just woke up a few minutes ago. I still feel kind of crappy, but not nearly as bad as before.
