To take your Ambien while driving, about the 20 mile mark from your house.
Usually done in the hopes of maximizing your sleep time.
The only issue being if some "fucktard" crashes and causes traffic or some sort of delay before you reach your destination. Then you're fucked cause Ambien takes no prisoners!
"Holy shit we were busy tonight!!! I'm sooooo ready to play some "Ambien-Chicken"!
Hey Autumn, reach in the glovebox and hand me some of that Ambien...we're only another 20 miles from home...I bet I could make it!"
