I used to be able to handle dental work without any problem. About 15 years ago, I had a session that involved around an hour of grinding on a tooth to prepare it for a crown. That experience completely devastated me, and I've been in a disaster zone ever since.
Any dental work, except for something very minor, sends me into a serious spike that can last for months of torture. I don't think there's any real way around it. My dental team tries to help by using a drill–pause–drill–pause approach to minimize the impact.
I don't even want to write this because I know it might bring everyone down, but I'm in a deep funk at the moment. My energy level is zero, and compared to even a year ago, it has dropped sharply. They also discovered that I have chronic leukemia, which might be part of it. Or maybe it's a double hit, and my body is just telling me that the ride is over.
