What causes the tremor from coffee?

Question
What causes the tremor seen in heavy coffee drinkers, and is that related to dopamine like with Parkinson's Disease?
Answer
That's a very interesting question indeed. There's a bit of a paradox. In healthy people, caffeine causes a bit of a tremor in your hands, it reduces hand steadiness. Whereas there's evidence that it can protect against Parkinson's disease.
