Second what everyone else said, but at least you stuck with the lesser of two evils. I've always said that if you feel like you are REALLY going to cheat and can't stop yourself, then try to find some sort of "legal" cheat. While it's true that PB isn't allowed on induction, it is allowed later in the plan. I think you did well with just a tablespoon and not giving in to the cookie. Good for you! Just get back on track and you won't even be craving soon.
