The Depression can happen whether you use ES or not, and whether you do an enema or not. Sorry for the confusion. :)
I don't bother with dilating the bile ducts because I take very special care to soften the stones before I flush. I am currently using a combo of fresh-squeezed apple juice and Gold Coin Grass for this and it works great. Before that, I used a combination of the juice and Liquid Phosfood. As long as the stones are soft, there's no pain or difficulty.
I don't do a coffee enema because that would mean more stress on the liver to flush, and it's already been stressed enough. I use a plain water/salt enema to simply cleanse the colon. I also do one prior to the flush so my colon is clean.
Right, if the ES gave you diarrhea and things ran clear, they you were probably cleaned out okay.
