OK so obviously this doesn't happen to everybody but it has happened to me.
I take 2 mg copper with 60 mg zinc every day and have for a few years.
I started taking boron I think a bit more then a month ago.
I have been feeling crappy with the worst insomnia and a frontal headache that has gotten so bad this past week and only yesterday did I realize it was copper and only in the last hour I found that boron increases copper in the body.
Some of u may have seen my last post where I asked about raising selenium u can check it here:
