So I did Bikram again. It was perhaps not as awesome as the first time, maybe I was less distracted by the newness, and also I suspect the instructor not opening a window or a door periodically (like the first class I did) to air the room out contributed to my vague malaise by making me feel like someone was holding a sweaty sock over my mouth. But! I still felt great at the end and will go back.
Frankly, the hardest part for me is not talking for 90 minutes. So unnatural. Plus there are just so, so many jokes, way moreso than in a normal 90 minute period for me.
