You may need to up your Algin intake for the time being, as it sounds like you may be reabsorbing mercury. Also, be sure you're getting lots of vitamin C. If you don't handle fruits or juices well (many mercury toxic people don't), then try a Vitamin C supplement, especially if it has bioflavonoids in it. Bioflavonoids contribute to the action of vitamin C and occur in nature with vitamin C. We use a supplement called Citrus Bioflavonoids. For more info on what bioflavonoids do, Bioflavonoids.

Vitamin E is also important for mercury detoxification. It's good that you're not taking chelating supplements. Your tissues appear to be excreting more mercury than your body is able to eliminate without reabsorbing it. Try drinking more water and eating fresh (organic if possible) vegetables for the fiber.

Hang in there...things will get better!
