I hear you, Shifterred. There are some days that I care a LOT less than I do, other days, about staying precisely on track. There are some days where eating as much of the candy in my kitchen as I feel like it feels *great*--like I'm free, and autonomous, and so on. I had an inching-up-toward-3000-calories day last weekend, too, and I woke up the next day feeling fine about it, but also slightly freaking out that I wasn't freaked out by it: What does it mean if I can cheat and not care? Am I doomed?
But see, I felt fine partly because I knew that not every day would be like that. And I also felt fine because I saw that, over the next couple of days, the scale barely moved--I think I was up about .2 pounds, and they're well gone now, a week later.
I think it's OK to overeat and not care. In some ways, I feel like it's healthier than putting yourself in a cycle of blame-and-shame, one that reinforces a relationship with food that connects eating, however subconsciously, to sinning or transgressing. But you have to know the reason you don't care, you know? If you don't care because the day is "just one day," fine--it's just one day, move on.
But if it's because you feel like you were trapped and then suddenly free, well, start thinking about ways to create more freedom for yourself in the way you eat--a little piece of chocolate here and there helps me, as do about a hundred other it-feels-like-cheating-but-it's-not-quite things. Give yourself more space in your eating box, and you won't feel so much like you have to bust out of it, or like you dread going back into it. You know? That includes psychological space. Remind yourself that you have plenty of time, that eating foods that you *like* as well as ones that are nutritious is your job, and also take a minute to be happy with where you are now, instead of always feeling like you're saving up all your happiness for when you get to goal.
I hope you come back! And figure you'll be OK if you don't, for a while.
