Interesting that your milk thistle supplement offers beet and radish. The fresh form are potent Liver Cleansing juices. Might be interesting to make a cleansing radish/beet juice and mix it with some other milder nourishing juice (carrot/celery, cucumber/parsnip, etc) to see if that will help you into sufficient balance to do further cleansing.
The other thought is an amino acid called N-Acytl-Cystein (NAC). It is a precursor to the amino acid glutathione, which is what the liver uses to detoxify many substances, including Tylenol, alcohol, poisonous mushrooms, etc. It also eliminates heavy metals. Be sure to take NAC with 3x the amount of antioxidants (vitamin C, for example). The Emergency Room uses NAC in an IV for Tylenol and other overdoses.
