Hi Laura

I guess I was thinking more along the lines that dopamine deficiency/excess leads to behavioural character traits, way before the PD is apparent.

In my case I was

a) wondering if my excessive alcohol/nicotine intake is intertwined with the PD, whether to positive or negative effect

and
b) if my physiology will be susceptible to drug induced OCD, that I should avoid DAs like the plague !
