Day 9: Breaking my plateau...with whiskey and potatoes?

I went to a dinner party last night where my hosts prepared salmon and roasted broccoli especially for me.  For my boyfriend, they also made roasted potatoes because he doesn't eat green stuff, generally speaking.  Additionally, there were quantities of Scotch whiskey and wine involved.  I had just a tiny portion of potatoes, but I did help quite generously with the Scotch (it was a very good Scotch).  I was a little worried about getting on the scale this morning, but lo and behold, I was back to 211.8!  And my body fat percentage dropped a half a point!  And my bust, waist, and hip measurements went down half an inch each or more!  So I'm paying for the Scotch a little today with a slightly swimmy head (and a five hour drive ahead of me...ugh) but at least I did not throw myself off course.  Now to face a new challenge:  the parents.
