I love it, too. I've had PB2 in yogurt, and it's good. It reminds me of PB cheesecake.
Jif all the way, baby. I've tried Peter Pan, and it tastes too roasted for my tastes.
DISCLAIMER: I expect to lose this weight over the next 6 months to 5 years. I'm not going to feel like a failure if it takes an entire month to lose 1 pound. I'm going to feel like a success when that happens! I may offer advice that I'm currently not taking myself. Feel free to call me on that!
