Too much Epsom Salt for too long is probably not good - it's hard on the kidney. This site I mentioned before (www.sensiblehealth.com) has a different approach that uses no epsom salt. Fasting, apple juice, some Chinese Herbs etc. Take a look, read it through, open your horizon. I know what you're going through, I know misery myself. I have done three flushes and did not get the result others talk about here but I keep doing what I started. It is a slow process in my case but the combination of flushes and Chinese Herbs help me. I do NOT have brown tongue, NO extreme fatigue (I still get sleepy 3 hours after I eat) NO excruciating pain (it's very mild!). Rumbling in my stomach is still a problem and passing gas too. But even this is getting better. There is no blockage in my liver anymore but the bile circulation is still not 100%.
As you can see the recovery is a long journey but one should never give up.
