Drink coffee.

Take caffeine pills.

Not drive.

Drive as fast as possible so you get to the destination quickly.

Stimulant drugs, including caffeine, are not helpful as a way of avoiding fatigue. They may help keep you awake, but will not make you any more alert. Feeling tired is a sign that your body needs sleep, and the only way to properly address it is to stop driving and get some sleep.

7. Mirrors should be adjusted:
