> Scott but isn't that the opposite of calming? If it relieves vegatative states isn't that stimulating? I drink tea l cup hot and two bottles of green tea as mild stimulant although I read somewhere that green tea is calming. Confusing. Phillipa
Two different pathways can be affected by the same drug. Often, one predominates. One can have and increase in energy without inducing anxiety. Different people react quite disparately to caffeine. I know one gentleman who could not sleep unless he had coffee just before bed.
I think tobacco can be energizing and calming at the same time. I have never been a regular smoker, so I don't really know.
