So, I did that 8 hour game experiment in part because I was too headachy and congested to engage the story brain. Over the course of the day I felt really energized and inspired, and I figured that meant I was on the upswing.
Nope. Just super into what I was doing. As soon as I stopped: headachy, dizzy, sore, and tired. Opened up my mouth to speak and it was a creaky whisper. I think part of that was disuse, as I barely said a word to anyone all day (and nothing for the last 6 hours), but while my voice did improve a bit with warming up, it is definitely a bit torn up from post-nasal drip.
Good thing I still have some of my con supplies (crystallized ginger and cepacol lozenges). Hopefully I’ll feel better tomorrow, as it’s supposed to be D&D day.
