I am so scared! I have had several spells or episodes of dozing while driving. It takes an emergency for me to drive away from town. Well coming home today from letting my son run in the local Wal=Mart to get a game he had worked for, I fall asleep, almost home upon a rize in the road leading to railroad tracks; I crossed the land and came within a few swift movements of heading my 1990 Factory Chevy Van into a little Taurus! I came home, defecated and threw-up! My son had been talking to me as we were driving across this little burg with I just zapped out. I would just be devastated if I actually hit someone. This is not my first incident but it was my closest. what is going on? Help. CactusLil'
