Bile not showing as much

I have done 5 Liver Flushes using Hulda Clark 's directions. I have had pain in my left shoulder and left back, as well as neck for some time. I noticed signficant relief after the second flush. I continued to get a large amount of stones up through the 4th flush with fewer on the 4th. On the 5th there was almost nothing. I started using the zapper before the 4th flush and also did a parasite cleanse. I got a lot of parasites. However, my stool went to a light tan color. After the second flush it had been a dark brown. I figured I needed to do another flush and did the 5th one with little results. My stool still is light tan (almost yellow on some occassions). I quit using the zapper and it started to turn back to a brown, but not as dark as before. I started using the zapper again and it is now a light tan. Seems the Zapper might be affecting my bile flow. Any ideas what is going on with me?
