Hit me with a brick

I called in sick to work yesterday for the first time in my life. There's very little worse than being sick in another country. Thank goodness it was only a 24 hour bug. I couldn't even keep water down for most of the day. The last thing I ate was an avocado, I hope that this doesn't give me a taste aversion because I love them so, but even thinking about one brings that vomit taste back in my mouth. I don't think I ate anything that was weird, and I've been drinking the water since I got to Chile with no problems (it is potable and clean). Unsolved Mystery.
