I went on the SCD diet in 2007 and I have been in complete remission ever since. The only drug I take is pentassa. The SCD is not something that works overnight. It might take you months before you see changes. It also takes fanatical dedication for it to succeed, but it sure beats turning off your immune system like 6mp or humira do.
I had two massive rectal fistulas and BMs with white mucus and blood when I was diagnosed with CD in the colon and small intestine in 2007 . I followed the diet with fanatical 100% dedication, and within two months, all the mucus and the blood were completely gone from mt BMs.
By 7 months both rectal fistulas were healed up and have never returned. The only drug I was takeing was pentassa.
To this day, I am still symptom free and in complete remission. I still follow the SCD but not as fanatical as before. I suggest you read the book "Breaking the Vicious Cycle" which goes into detail about the SCD. You have nothing to loose by trying, and all to gain if it works for you.
