Kim,
I'm keeping you in my thoughts and prayers that Wednesday will go well. Drive safely.
Also, for what it's worth, I had very localized fasciculations (started on the bottom of my left foot) and they spread very systematically. First to left calf, then to right foot/calf, etc. I was two years in before I had widespread twitches. My first clue was falling on a run. Then, six months later, my feet started cramping while swimming laps and that's when I noticed the fasciculations.
