Strangely, given the fact that I had constipation for years, then diarrhea for several years and now a few major food intolerances, you'd think that probiotics would have helped, but I have never experienced them doing so. I have mostly followed a healthy diet with a lot of vegetables, so maybe I have already gotten whatever benefit I could get from there. What generates this illness I used to believe was some kind of permanent damage or neurological damage, but now the horse I am backing is XMRV or its family of retroviruses.
