Something I have found after doing this for 4 years (and maintaining my 80 lb weight loss) is that I do not consider a "chip here and there" a slip-up at all. A slip-up would be eating 5 servings of chips! If it were even
possible for me to just eat a couple of chips - that would be a huge victory for me!
One thing I have learned by watching the "normal weight" people in my life is that none of them abstain all the time and they
all indulge once in a while. It's harder for me because I am a binge-eater, and I have a lot of trigger foods; but I now, occasionally, allow myself indulgences. When I stopped being consumed by guilt for eating a small piece of chocolate, the journey became easier and a lot more enjoyable. A major unplanned binge is a different matter...
I understand it was
unplanned eating, and that can be
disastrous; however, sounds like you kept in under control - bravo!
