I agree as well.

YES. So, this is where being _committed_ makes the difference.

I have many rules that help me with this one is "feeling hunger is normal" and "being uncomfortable getting back on track is normal". (this rule is less refined, but key to overcoming falling off the wagon) And "admit when you fail, and try again", very key to dealing with getting started, or restarted on a good thing in life.

The self-training you mention was what I signed on for at the beginning, knowing full well this is normal, so it's not so bad when I have to do it.

Likely others have similar experiences.
