Truthfully, I didn't notice massive changes until week 10 or so but I felt little changes along the way.  Weird but true. :-)

...but others noticed before I did. :-)

I keep reading the women's inspirational document for encouragement; it is in the Media Gallery.  It has a whole bunch of testimonies about when ladies started seeing change.  I am on W2D3 of my first challenge.  I don't see anything yet but I feel like things are going on behind the scenes.   I am only focusing on week 12!  The rest is just process!
