I have the same craving (that and chocolate). I did try the atkins chocolate peanut butter protein bar... it really does taste like peanut butter! I was shocked. I don't find the bars stall me as long as I eat one in the morning (I replace my eggs and bacon on the weekend with a low carb bar... it's a nice change without the hassel of cooking). I've been planning on picking up some sugar free peanut butter.. but to be honest, I have reservations that it'll taste any good. Then there's the fear that if it does taste good I'll over-do it.
