You're not "cheating," you've not "fallen off the wagon," you haven't "failed," you're just making poorer choices about how you eat, you're dealing with your addictions to your old "comfort foods," and you've simply been "eating outside of the program."
I like to stop each week for a few minutes, usually on Sunday morning, and consider what I've eaten over the past seven days. I come up with an honest number, a percentage, by volume, of the non-raw foods I've eaten over the last week. Sometimes I'm shocked at how much I ate outside of the program. When I'm in the high 90's (99% raw last week) I congratulate myself for doing so well. When I'm in the 80's (or wherever), I resolve to do better next week.
Over time I'm finding new "comfort foods" that are also Raw and Vegan.
I don't beat myself up over it, and I don't share the number with anybody else (well, except with you). It's my personal business. I just remind myself that this is MY chosen lifestyle, and then get on with my life. This is a lifestyle choice, not a religion, and it's MY choice.
