I am far from any sort of knowledge bank about the SCD as I didn't have the stamina to stay more than a couple days. But there are a few on here who will have info for you. There is also a yahoo group for the diet.
I think there is something about change in stool for the first few days as the body adjusts. Hang in there and hopefully someone will come along with real info for you!
