Char,
Please be careful. I know this type of fatigue can hit hard and fast not giving us any time to prepare. But I worry about you sleeping in a rest area. I'm glad you did stop because falling asleep at the wheel is not a good idea

but I just hear so many stories of women being abducted at rest stops.....I just don't want anything to happen to you. Sorry....I'm just a worrier.
I hope you're feeling better now. So, you gotta new car?!
