I just finished lunch. I started to have a sandwich, thinking to myself 'just this one won't hurt', but then I realized that I had promised myself that I would stick with this for the entire two weeks. And that 'just one' has a way of becoming just three or four or more. So I didn't. I had an on plan lunch and truethfully I'm feeling pretty good about it. Yes 'just one' may not 'hurt' physically. But mentally it can make a MAJOR difference in how I think and feel about myself. And THAT is enough to derail me BIG time.
