I had horrible hand tremor on Depakote and I know that I lost an interview for a position for which I had a uniquely fitting resume due to this. I also lost a teaching audition - the marker trembled and shook in my hand, spurring an anxiety attack. It was horrible. Normally, I am poised at the white board, but the tremor did a number on me. I eventually discontinued Depakote and the tremor went away, though it took awhile.

There is no antidote to tremors caused by Depakote. If the tremor is caused by antipsychotics, though, there are antidotes medications, e.g. Cogentin.
