Hi Chuckput.   You are right regarding the bigger movements of the bow.  I find for music where the bowing is more "energetic", then the impact of the shaking is much less.  This is good news in the sense that it doesn't stop me from playing a lot of repertoire, so when I need to play at a recital etc I try to pick music that works with this, and much of the pieces we play in Orchestra fits in with this as well.  

Like you I've also found moderate alcohol can be effective.  Studies indicate the equivalent of 30ml of pure alcohol has a tremor reduction of ~60% (if I remember right) within 30 minutes of consumption.  I might see if I can introduce this strategy into my practice and performance regime more often.  I do enjoy a good whisky so this shouldn't be too much of a hardship.  In fact, I might just find myself practicing more often...

My shakes have worsened enough now that I'm probably closer to your dear old dad.  Does make for interesting and humorous times though.  Just today I was getting Sushi for lunch and while taking a piece out of the display cabinet my shakes caused it to completely explode and disintegrate all over the other pieces.  Don't know why but it just made me burst out laughing.  I guess you had to be there.

If I find work out any other strategies that may help with playing with a tremor I'll be sure to let you know as well.
