Hey!
Everyone seems to be saying Oh, that's all right, Oh, that's no problem you'll be fine, Oh, everyone does this...
So let me be the voice of the other view, which is, No, it's not all right that you lost control with food and ate so much that you were sick. Yes, it is a problem when that happens. No, not everyone does this.
You have learned something about yourself, which is that you can get "triggered" by certain off-plan foods into overeating. That's a valuable thing to know.
If it's just one day, then yes, there won't be lasting harm from it as long as you get back on plan. But your weight loss may stall for a few days. Also, you'll probably need to be careful, lest this incident turn into more such incidents and more frequently. This is where folks often fail in their weight loss plan--don't be one of them!
Hang in there! Keep on going!
