Welcome! There are lots of us ex-vegans here. I recommend you read The Vegetarian Myth by Lierre Keith. You don't have to eat a lot of meat to be primal but if you read Keith's book with an open mind, you will completely stop believing in vegetarianism. Go to Welcome to Mark’s Daily Apple | Mark's Daily Apple if you haven't already. The books are great too, but you can learn everything here. Good luck!
