drinks, for both combatting dehydration and for energy / keeping awake are good.
snacks / sandwiches important if there are long stretches of road with nothing and no-one around.
don't forget your cd collection. music to help keep you awake is a good thing.
pay attention to the local radio station frquencies, for traffic / weather bullitens. you can save yourself stress and even your life by knowing that pulling in for the day far easrlier than planned will keep you off the road rather than drive through a blizzard. ( specially as you haven't driven in snow )
Always park your car when you need to adjust the radio to hear a local station, and make a mp3 CD with all your favorite music, so you won't have any distractions changing Cd's when you are on the road.
