why??

I've been sick all day. Got up feeling fine had some breakfast, sat down on the computer. A couple of hours later I was puking my guts out. At around mid day I went to bed feeling just as bad as before (with a splitting headache) and was out for like 5 hours. I had to get up and return a dvd, and went to the drugstore on the way there (bought some medicine for my upset stomach). After I got back, the puking started right back up. >:-(

In my feverish dreams, I was dating a guy that looked just like Shia LaBeouf. I don't even find him attractive. At all. I have the worst dreams when I'm sick.
