"My symptoms actually more closely resemble someone with a fast phase one liver metabolism."

Have you tried plenty of turmeric, milk thistle, and dandelion?
those are supposed to help with detoxification. When I feel the worst I drink a cup or two of Triple Leaf Detox Tea. That usually helps. Have you tried magnesium malate? Creatine? I think eating extra soluble fiber also helps, as it makes less of the bile get recycled, and more of it recycled. Much of the toxins in the liver are excreted through the bile.
