To back Missy up, I've found that magnesium supplements helped me a lot. Mercury interferes with mganesium.

Also, beware of milk and mercury. Studies have shown that milk prevents the elimination of mercury. The researchers have no idea what it is in milk that causes this to occur, but the differences between urine-mercury between milk consumers and non-MC are dramatic.

I've also read studies saying that milk actually causes calcium-utilization problems like bone spurs and osteoperosis. They say it had to do with the process of pasteurization changing the way calcium works in the body. These problems didn't occur with un-pasteurized milk.

Interesting.
