You my friend ,

is suffering the same thing as I do! 
I couldnt find anything about it, I mean I am also unsure what caused this and what exactly im suffering from.

Few things:
- How bad is the shaking.
- Does it occur every single time or only at times.

I have minor case of my hand shaking when holding spoon etc, and moving at a slow motion (and being conscious about it). My own way of overcoming it is to move at a slightly faster rate and to ignore it (be less conscious about the process of shaking)

EDIT: It might be a result of bad strength control too. I'm born with extremely bad control of my strength, always using too much strength. I will use too much strength to open packaging and cause food to fall all over the place. (potato chips packet always tear at least opening and 1 of the sides). Now I always limit the strength I use, resulting in quite severe shaking of my hands when I'm trying to adjust my strength.

Im having the same thing but not my hand but my leg. I asked the doctor if this is parkinson and he said no. When i do some research, it found out that masturbating can make your hand and leg become like this. So, less masturbate. P

i think it's tremor..
