Update: I have the shingles, which is oodles of fun, and the doc gave me some pretty potent antiviral pills. I took several the first day and got a little loopy, "teehee, this sucks, oh well, heee..." but thought nothing of it.
The second day I took several more as per instructed, and that's when things got weird. I started to feel disconnected from reality, my brain began vibrating like a drone was in there trying to escape, my IQ dropped by at least half, and I could only see into the future. The present was gone, but I knew what was going to happen 2 minutes before it did. I became the Stupid Nostradamus.
Apparently, that's very bad.
Called the doc, and he said if it got worse in an hour, go to the emergency room. Things eventually improved, but it was a pretty shitty night.
Hope that Peak Dorian is still ongoing, climaxing even, as it were.
