Scary. That is one of the biggest reasons I quit work. I was nearly killing myself (and maybe others) every day falling asleep at the wheel.
What is your situation as far as working and stuff, mommie? Have you applied for Social Security Disability yet?
And just FYI, the medication that finally helped me bring the CFS to a tolerable level is Ritalin(generic is Methylin). I know it gets a bad rap, but it is night and day, life and death for me. Provigil is another one that seems to help a lot of people, and it is supposed to be non-addictive and help weight loss.
Good luck. Hope you can get the CFS to a point that you can drive safely!
