I've been having the same problems with insomnia and depression. And I did have an episode of buzzing in my head the other day. I had my Amalgams removed last month and since then, I've been dumping a lot of mercury, especially from my brain. I've also been having crazy mood swings, too...not bad enough to check into a loony bin, but worse than I had before my removal. What type of detox protocol are you on?
