You know what?
It's not fabulous to beat yourself up about it (i know, we all do it), but the plus is that you recognized that you were making a bad choice and that is a step in itself!
At this point, you just pick yourself up and get on the horse again. Nobody ever said humans were perfect
My only major advice is to be careful about denying yourself points. You HAVE to eat your points for the day. Working out is a bonus but it's very important not to starve yourself. I learned the hard way that it just makes things more difficult.
How did your weigh-in go? Im assuming you've finished your meeting now
