Thanks for the kind words, both of you! I'm feeling better now, although not 100% yet. I decided to give my back one more night of rest before diving back into the exercises, but I did do a bit of yoga today and it felt really good to stretch out those muscles!
I'm completely exhausted tonight. Not sure why, but I am. I think I'll make a nice cup of hot tea, take a steaming hot bath and go to bed early. What an exciting life I lead, right?
