I worked with a guy that had a bad tremor, not only his hands but his head as well. He drove hwy tractor without any problems. It was similar to Parkinsons as well. Maybe the same as you have. He said he was looking into brain surgery to correct or improve it.
The Doc talked to me about that type of surgery. I'm too dang old to have someone playing with what little brain I do have. Besides the meds do a pretty good job most of the time keeping the trembling down to a dull roar.
