My boyfriend recently fell asleep behind the wheel and flipped his car off a ramp over the highway. He was crossing over the ramp and rolled down to the main level road. Now I feel like as soon as I get into the car, I feel an overwhelming sense of tiredness like if im going to fall asleep. SO I always wear sunglasses because I feel like it some how makes me more awake....? Weird I know. But its my comfort.
