At Do not be afraid! When the meds no longer work, we can be glad there is another option. As Gordon said to Dr. Burchiel, "Go for it, Doc" and when I asked him how it was (he was eating lunch in the ICU), he said "Absolutely Fascinating". You might think some people go to a lot of trouble for something interesting to do but that's Gord. He had thalomotomies because of terrible tremors.
