Thanks so much Tim, for the list of books. I am a bit confused about the Sinclair book though. Is it called  "IBS Starch Free Diet" or the "New IBS Starch Free Diet"? Are they two different ones or the "new" one is just a newer version?  I will try searching the others.
ALso, Tim, could you tell me more about L-Glutamine? I don't think I have come across any info on it yet. How does it work? I am also taking fish oil which was suggested by my rheumatologist, but he might call the police if I tell him about my diet change. He has already complained to my PCP that supposedly I am not open to accepting treatments just because when he and all other rheumatologists pushed the TNF blockers -- I just wasn't too enthusiastic. It has been a long and frustrating journey with the medical "care" industry -- but I am trying not to get worked up about them and trying to stay positive for the sake of my body and its ability to heal. 
I am on Sulfasalazine -- does it affect this diet in any way? Is it a big problem if we are trying to heal the lining of the gut?
Thanks.
