liver cleansing & diarrhea

I have done dr. Clarkes liver cleanse (olive oil & grapefruit) 6 times and for the first 4 times had a lot of stones, about 3oo to 400 stones each time. I then did my fifth and 6th flush with mostly chaff and a few very tiny stone released. The oddest thing I noticed since the 6th flush was I've had diarrhea for about 2 months now, everyday! The other odd occurance is that It started seeing a psycologist the next day. I don't know if the diarrhea is realted to the flush or the psych? or both?
any suggetions or words would be appreciated
