Becky,
The coffee cup example is sooooooo true. I once before treatment when to pick up my coffee cup, and it felt like led, I wasn't expecting it, and when I went to pick it up, coffee went everywhere. And many other times after that.
Sometimes if I'm washing a window, and I'm washing in a clock wise manner, my arms, start to get heavy, and I can't hold them up and have to switch. Almost like your out of shape, but not.
I wonder how many MG'ers spill there coffee for the same reason.
Love Lizzie
