Can mercury cause mood swings? I find that sometimes I have a black mood out of nowhere and am very irritable. I know that women are supposed to get this with PMS, but as my female cycle is mixed up, I don't know if that it is.

I know that Bipolar disorder can be influenced by mercury, so I was wondering if moods can be a lesser symptom of that? I wonder sometimes why I get moody for no apparent reason.
