Next day guilt

I suppose it's a good thing, I've reached the point that I have guilt for eating something I know I shouldn't have.  Was in NYC yesterday. Had a light breakfast, no lunch, no snacks, but ate almost my whole dinner which was chicken and pasta, appetizer, and a couple drinks.  Also had a few bites of cheesecake.  Really feel like I over did it. Looking back on past eating habits, this was nothing but I'm still in the pursuit of those two pounds I need to reach my goal. Because it was my birthday I gave myself permission to indulge a little.  The guilt still came.  Today is a new day and we are back on track.  Telling myself...let's get this done...2 pounds to 25 and then we can move forward with a new goal.
