Well, I definitely overdid it. Not sure if it was the exercise or the fact that I vacuumed half the pool afterwards. Normally I can vacuum the whole thing so this wasn't an unreasonable proposition when I decided to proceed.
I crashed yesterday afternoon to the point where I dipped into my leftover prescription pain med stash. I spent the rest of the day on the couch covered in blankets watching Farscape. I was fried and sore. I'm still tired today. You would think that I just got back from climbing Mt Everest rather than a lame stretching session in the pool. OMG when is this going to stop?
