Richard and Tatertot have both recommended in the past to mix things up - using multiple sources of RS, and perhaps switching between them, and going some days with little to none, IIRC. If you think about the sorts of traditional "gourmet" diets that Paul Jaminet talks about, they normally don't involve eating the same exact thing every day.
Both Richard and Tatertot and Dr. BG also talk about some or most people probably needing probiotics. Theoretically, some of the symptoms that folks report may come from not having enough of the necessary bacteria to consume the type of RS they are eating and to generate the enzymes that break down the potentially toxic parts of foods. Some people have reported lessening of symptoms after adding various probiotics, either from food sources or capsules.
