Kimmi, don't feel so bad. We've all been there! I had a doctor's appointment on Wed at 12:30. He was running late and didn't get to me until 2:30. By the time I got out - having had only fruit for breakfast - I was starving. I drove like crazy to get to the nearest restaurant, ignoring the Arby's across the street and ordered the salad bar so I could eat right away. I did eat the good stuff, but I also ate the other mayonnaise filled types of salads.
You just wake up the next morning and start again. I really wouldn't want to be a celebrity, but I envy them for having their own cooks and private trainers.
