The morning after

Note to the wise: Don't drink the night before you get a virus. A biological virus, not a digital virus.
Yesterday I was sick. One of those mini-flu things, a 24 hour "bug". Ug. I won't go into details, but suffice to say it wasn't fun.
Today I feel ...not as sick, but really groggy. Ever feel stupid? Like you can't get your brain to work as well as it usually does? I'm stupid today. I am able to process information, sort of, but very slowly. My fingers are stiff so it is hard to type. My back and leg muscles are sore, but don't ache like they did yesterday. Thankfully. That is not the way I wanted to spend my day off.
