I'm in agreement -- if the cravings aren't gone, go back to P1 for just a few days. You already know how good it feels to be "clean", and that will give you some more motivation to continue on P2.
I'm a P2 newbie myself, and I can relate to fearing the freedom that this Phase gives us. I just try and remember that this is a lifetime change for me, this is the way I want to eat for the rest of my life. I would almost much rather stay on P1, but I know that is not realistic. I am adding in one thing new each week (this week is brown rice), and we'll see what the scale says on Friday AM. In the reading that I've done on this forum, it looks like it will just take some experimenting to see how my body reacts to the new things I introduce.
The boys brought home a box of doughnuts from church yesterday, and the beautiful pink box was sitting on my kitchen table. And as I looked at it, I just focued on the grease spots on the box, and I had no desire to put that junk inside my body. That was just such a huge victory for me.
Hang in there, Kate, you can do it!!
