I am halfway thru the Paleo Solution book by Robb Wolf. It is one of the most eye opening books I've ever read. I started reading it because my daughter has Celiac and her symptoms have returned after being gluten free and symptom free for a year. Our whole family is now going Paleo. It is hard and is taking some time to get used to, but I'm hoping it is the answer to healing.
I am in the same boat. I have been gluten-free since last October, but I am sure I have food intolerances. Tried to do elimination diet twice, but I just can't stick to it! I am strongly considering going Paleo, but a "modified" version. I ate Paleo for several days last week, but was starving without a small amount of rice or white potatoes. Been looking at Robb Wolf's web site, and it is very informative on the Paleo lifestyle. Best of luck to you!
