Welcome to the group! keep watching all of the videos and read everyone's posts, I think it is a great way to learn. Also, don't forget to look at the recipe section there are so many good ideas there. Dr. O also has a book with recipes and there are many others online with books with grain free recipes. spunkycoconut.com, elanaspantry.com are two good ones that come to mind right away, they both have good cookbooks too. If you are on facebook “grainfreemom” is a good one too, she has a website too, but don't know the name of it right now.
So glad you are already beginning to feel better. Take one step at a time, sounds like you have a good dr. I would ask about probiotics and ask to be tested for leaky gut syndrome. There is probably a bunch more things you could be tested for too, like maybe candida. Best wishes and if you have questions this is the place to ask if we don't know Dr O is full of GREAT information and he is good about reading these posts and replying. I also am so glad to have found his site!
