Thanks, everybody. I'm slowly mending. The worst problems are the double vision and dizziness caused by the concussion. It's been a week and neither of these issues has reduced even the slightest amount. Next Tuesday I'm seeing a specialist who may be able to do something with my head...though I keep picturing the doc walking into the examination room carrying a large hammer to tweak the alignment of my eyes.

p.s. one benefit of double vision, there are twice as many ETS members! :-)
