Tae Kwon Do, into work.
I'm feeling better today, and think that whatever the problem was, it was something that won't be there tomorrow. But it's hard to say for sure. I'll be going in under the same conditions; 5 hours of sleep and getting up way too early.
If the problem was sickness that I no longer have, I'll be fine; if the problem was sickness that isn't showing today because I had a rest day today, well tomorrow will suck too unless it's gone by tomorrow; if the problem was something like food poisoning then I'll be fine; if the problem is just that there's something fundamentally wrong with me that causes me to feel really really sick and vomit after light exercise (no seriously the exercise I was doing as part of tae kwon do was something which I should be able to do pretty much in my sleep, it's so easy; I do worse than what we did then often enough)...well then.
Guess I'm really screwed then.
So tomorrow will help me narrow things down quite a bit. If I am fine, then the problem was sickness I no longer have or food poisoning but either way it was a one-time thing that means nothing's to be concerned about.
If I'm not fine tomorrow, then the problem's either sickness I still have or something is just fundamentally wrong with me and neither option is a particularly pleasant thought to face. (It's never a good thing when the better of the two options is "I am really really sick".)
Anyway, I'm typing this just before heading to bed, so.
Gotta sleep now!
