I'm not sure what did it. Either my body finally got comfortable with the idea of losing weight, the unintential semi-fast during travel, or the 1 day carbo-load feast that came about a week later, but this morning I hit a new low of 213.5!
Yesterday, I put on a pair of pants I haven't worn in at least 6 months, maybe longer, because they were too tight around the waist. I guess it's the dreaded middle-age spread, but that's a topic for another day. Anyway, these felt fine. My pants today are a size larger, and I'm having to hitch them up constantly. Maybe in another week or two, I can go shopping in my closet for the next size smaller pants that I put away when I got pregnant.
