Does anyone have any experience with bikram yoga?

I tried bikram yoga for the first time yesterday (1.5-hour class, 105 degrees F), and I’m feeling like I was run over by a large vehicle. I probably pushed myself too hard. I am far less flexible and strong than I had thought.

If you recall your experience with starting it, how many times did you go in the beginning? Did you wait one or two days for your muscles to rest or did you jump right back in the next day? My wife’s been doing it for about 6 months, and she’s a bit hardcore, so I can’t follow her lead with stuff like this.

Note: I’m doing this as part of my attempt to try everything possible to help with my back.
