Yesterday ended with severe stomach upset. I went to bed early and rose late. After breakfast I returned to bed for a nap.
Regardless, I hoped to get in a mini-T'ai Chi Chih practice before I left for work. And I did. At the end of practice I still felt extremely tired but drove to work anyway. I finished my workday then resumed my T'ai Chi Chih practice in front of the magazine rack at the library. (I don't know that I'll do that again ... it's too distracting.)
I feel a bit better now but it seems to me that it will be another early-to-bed night. Hopefully tomorrow I'll feel better.
