The issue isn't just the mercury itself, but the candida and/or parasites, and nutritional deficiencies due to impaired absorbtion. Then there may be adrenal problems, and/or serotonin problems. Try to treat all of these issues can be very helpful in regaining strength and well being. Depression may be a result of serotonin being low. Licorice root can be very helpful as far as mood. I used to use St. John's Wort for this, however after a while I became sensitive to it. Licorice root is also antifungal and helps with detoxification. Licorice root tea is my favorite supplement. It also tastes great. Doing parasite cleanses and taking antifungals is an important part of the strategy. Wormwood, black walnut green hull extract, and clove oil are very antifungal and antiparasitic. These three together are potent against both parasites and candida. Wormwood might be the most potent antifungal. Just be careful when using Wormwood and clove oil, as they may be toxic if the intake is too large. There are some liquids available with all 3, or you can buy the extracts and clove oil separately. I think these have been very helpful for me. I first took the Wormwood as part of a parasite cleanse, then noticed that it was doing a great job diminishing the candida related problems.
