Try doing coffee enemas. Since Liver Flushes make you sick, either your liver isn't functioning very well (as in sluggish) or it is full of parasites. Either way, a coffee enema would help the liver function better and get rid of toxic bile.

The following may be of help:

The palmitates of coffee enhance glutathione S-transferase which is responsible for the removal of many toxic radicals from serum. Finally, the fluid of the enema itself stimulates the visceral nervous system promoting peristalsis and the transit of diluted toxic bile from the duodenum out the rectum. Because the stimulating enema is retained for 15 minutes, and because all the blood in the body passes through the liver nearly every three minutes, these enemas represent a form of dialysis of blood across the gut wall.....As a medication, the coffee enema is in a class by itself. While other agents classed as choleretics do increase bile flow from the liver, they do little to enhance detoxifying enzyme systems, and they do not ensure the passage of bile from the intestines out the rectum. Bile is normally reabsorbed up to 9 or 10 times before working its way out the intestines in feces. The enzyme enhancing ability of the coffee enema is unique among choleretics. Because it does not allow reabsorption of toxic bile by the liver across the gut wall, it is an entirely effective means of detoxifying the blood stream through existing enzyme systems in the liver and small bowel. Because clinical practice has shown coffee enemas to be well tolerated by patients when used as frequently as every four hours, the coffee enema may be classed as the only non-reabsorbed, effective, repeatable choleretic in the medical literature.

Liver Flushes made me sick until I spent a month doing parasite cleansing.
