I'm sorry to hear that, Dancer; hope you feel better soon! My friend's daughter had it, and it took a couple of months for her energy to return, but then she was good as new! Use this time to catch up on reading and be catered to, if you can. (easy to say, hard to do - I know I would be frustrated if I didn't feel well enough to do everything I wanted to do.)

Take care,
Kathy
