I've seen on some other forums from the US that a lot of people with TS are getting their neurotransmitter levels tested. These seems like a logical place to start treatment. I'm wonder where one would get a test like that done in Canada. Those people were going to what they called an "environmental doctor." Would that be the same as a naturopathic doctor up here? Has anyone ever had one of these tests done? What were your thoughts on it? Who did you go to? Does this seem like a good place to start treatment?
