Two articles of potential interest (and I think they sort of go hand in hand):

Will be interested to hear about the GI Effects results. I haven't had that done, but I did have a CDSA 2.0 done last August. You can see the results (and Dr's comments on it) https://www.mediafire.com/?z3vzqjmcgu941b1

Good to hear about the improvement on the TMI front dlee, seems to be a common result of adding RS in.
