Be careful not to get too fixated on food sensivities. For that kind of money I would rather "fast forward" and do a series of colonic hydrotherapy sessions. Be brave! I've done 2 and the third and last in 10 days time. For a month now I have been eating bread and cereal (small amounts) every day. I am not saying I'm cured, I've got a sore stomach and a lot of wind and bloating but many of my usual reactions just haven't happened. I have done several parasite programmes (important I think) and, as I said before, avoided certain foods for a long time now. For a probiotic, I am taking a product called Prime Directive (Australian - anyone know anything about it?) whcih says on the lable is a blend of fermented organic whole foods. The colonics lady said to take this along with barley grass. I wasn't going to buy it (o no! not another product!) but it seems to be making me feel good. (early days!)
When you say P & B cleanse do you mean P&B shakes? Aren't you reacting to psyllium?
I bought a zapper from a friend who lives locally. I need to try it again but, for all the positive uses of zappers there are limitations. It is ineffective in reaching some internal organs (I think, bowels?) and brain so you still have to take Clarkia (or whatever programme you prefer).
I did do a laboratory parasite test. That was useful and worth the money.
