Facing liver problems during parasite cleanse

I have been trying to clean parasite in my body for over 6-months. For 5-months used black walnut, wormwood, and clove protocol (with 15-days break after taking it for 15-days), and for 30-days used Diatomaceous Earth (without break). During the process took Milk Thistle and Chlorella tablets to assist in the cleansing process. Post June 25th, I'm not taking DE or black walnut protocol to give body some break.

Diatomaceous Earth seem to have worked well. Though parasites are still there and I'll be going back to further parasite cleanse soon as crawling and die-off symptoms are still there.

However, now liver problems have started. BM has become irregular, only once in 3-days, indigestion, and related problems.For the last 1-week, almost not eating and only on juice and some other very light food due to indigestion.

Yesterday finished liver flush with Dr. Clark's protocol, seem to be painless (did fasting 3-days before with a lot of apple juice leading to the day of the flush). Saw some yellow/brown segments floating in the water, and assuming they might be gallbladder stones (unless I'm mistaken).

While diarrhea is still there (1-day after the flush), I'm wondering:

- what could be the reason for liver problems (a bit worried, as the liver seem to quite low in activity)?

- what can I do to restore the normal liver function? : Any supplements, herbs, food habits?

- after how many days should I go back to another parasite cleanse?
