My doctor told me that with this disorder, there is elevated dopamine in the brain. I wondered how that worked because I don't seem like I'm happy. Dopamine is the happiness neurotransmitter in the blood. And I smoke cigarettes which opens up the dopamine receptors of the brain. I must be getting more sunlight and dopamine in my brain than anyone. The amount that I smoke. I also read a Schizophrenia book that said the same thing. I am curious what effects elevated dopamine alone had. If there is an incapacitation.
