Nat, welcome to the beach! Glad you are thinking of a lifestyle change. This is such a healthy way to eat, for life!
I must honestly say that this diet is pretty hard to do without reading the book first. It really explains much of what is behind the reasoning to do many of the things Dr. A recommends. I realize you've already started, but take a look at the FAQ here and read the book as soon as you can. You may find that you need to start Phase 1 over again to really detox if you've been eating things that aren't allowed. Even a tiny cheat in Phase 1 can really mess up your detox.
That said, I'm glad you are here and look forward to hearing all about a second healthy pregnancy!
