So I have to drive 9 hours to New Jersey for my friends wedding (tomorrow, June 9). I'm horrible at directions, but thankfully I have a gps. And yet I bet I still manage to get lost or turned around somehow. XPAnyways, I get really sleepy when I drive so I was just wondering what people normally do to keep themselves awake on long drives? Caffeine and music I'll have but is there anything else?
