I know someone who recovered from a horrifying depression 10 days after their amalgams were removed, plus a bit of homeopathic detox. I also know someone who had to wait for 2 years of hardcore mercury detox treatment from an expert in the field before seeing any improvement. I had my amalgams removed 4 years ago and haven't had any improvement. But i've had plenty of testing done which concludes that i'm loaded with Hg. So that's what i cling on to. I think if someone's depression is starting to lift, it's probably a good idea to add some Omega 3 and probiotics maybe. As for psychiatrists, i recommend the book "A Dose of Sanity" by Sydney Walker, a psychiatrist and neurologist himself, who enlightens us to the uselessness of a psychiatric diagnosis, psychiatric drugs and therapy.
