I can't thank you all enough for the kind words!
I don't know why, exactly, I fell off my plan. It began on Sunday - and just trickled on along each day. I was home from work on Tuesday and Wednesday because of snowstorms - which again, prevented me from going to the gym, and one day just turned into the next. I have recognized that a big factor for me is the PLANNING ahead. At work - I bring my lunch and I don't HAVE other choices at my fingertips. That helps.
I did go to the gym at lunch today - and feel good about doing so.
Thanks again for the support and PUSH that I needed!
