I go to bed, and when I get-up the next morning I try to do the best I can and not think about things I can't change.

This article has lots of helpful tips. Mostly around how to learn from the experience and not beat yourself up:

I don't mean for this to seem sarcastic, but I...just get back on.

I stop eating whatever crap I might have bought, and throw any unfinished portions away (no matter how much is left or how much I spent on it). Then I go back to eating what I should. That's it.

What helps me a lot is that I now feel unbelievably lousy when I eat crap, so I crave it far less as time goes on. Sugar makes my pulse rate rise, and I feel anxious. Wheat gives me a monster hangover the following day. Having observed this enough times, on enough "cheats," I'm in no hurry to experience it again, so junk food is far less tempting now than it used to be. What was once "comfort" food has become "discomfort" food.

I love this Chinaeskimo as I too have so struck by what looks or sounds good from past years and when I try it (rarely) Im kind of disgusted.

You already did the right thing I think - you got back on track!!!

We can all only control the present... its all about MINDFULNESS. Forget the less than perfect food choice of the past and control the present!

Also, I have really found that never getting to hungry by eating regular meals of protein and healthy fats and some carbs.. I just never crave sugar anymore EVER.

hang in girl.

Realize that you're human, don't feel guilty about it, learn from your mistake, and move on. Eat to live, not live to eat. The trick for me has been to not over-analyze the situation or try to search for a "deeper meaning" that isn't really there. My love of eating Paleo comes from a love for its logical simplicity, and the simple truth is that there's always room for improvement.

For me, falling off the wagon could mean one of two things; 1) gluten/processed sugar exposure or 2) gross overeating.

If I have a gluten/sugar exposure I just try to extend my fast a little the next day. Maybe have salmon or sardines to break the fast for the n-3 boost but that's about it.

If I have a day of 12,000 kcals (all or mostly all paleo) I just try to figure out why; am I under recovering, did I underway for a few days, is my workout too hard. Again, I'll extend my fast but that's more because I'm stuffed.

I plan to drink a 30 pack of beer between Friday and Saturday of this week. To compensate I'll eat once on those days plus once on Sunday. Meals will all meat and veggies. Plus I will stay very active during those days. I'll return on Monday with no problems.

I just move on, it's not the end of the world if you eat something "not paleo". Just continue eating the right foods MOST of the time, and a cheat here and there isn't a big deal.

Just do it. (As generic as that sounds.) It's okay to make mistakes, that's how we learn and grow. Accept it, get over it, move onward in life. Life is too precious of a gift to stress and worry about falling off all the time. Just get in there, attack hard, and go forth.

True, hungering motivation comes from within. People/articles/encouragement might help at first, but you have to become determined. You have to find it within yourself to get back on, and stay the course.

Every single day I wake up, the first thing I do is count my blessings, then tell myself the kind of day I'm going to have. "Today will be a strong day. I will work hard. I will play harder. I will eat good foods to feel awesome. I will be the best me ever and nobody will change that."

Stay strong.
