It could just be die-off. I used to get severe upper stomach pain from milk products, and especially chocolate milk or chocolate ice cream. I would literally pass out from the pain. After Zapping for a long time, and drinking Kombucha Tea, I was able to stop this, but after lagging for a while on both, it came back. I am almost certian it has to do with toxins. Kombucha Tea, is very detoxifying and nurishing. I highly recommend starting on it. I've never felt better then when I drink Kombucha every day! Any way, as for your current problem, keep up the Zapping, at least once a day for 2 weeks, but if at all possible, 2-3 times a day. You are fighting a big battle with getting the toxic critters out of you before getting reinfected. ( parasites feed on toxins, so does candida.)
