How can I pack a bag for a 16 hour trip if I get car sick reading, sleeping, and watching movies? I get very hungry and very bored, please help!

Pack a large bag with lots of water (and some juice). Bring some Ibuprofen in case of headache. Bring snacks (pretzels, chips, crackers, fruit, or anything else) and money so that if you stop along the way you can get something to eat. If you want, bring a pad of paper and a pencil and write a story about where you're going, and also colored pencils or gel pens and a coloring book. Think of car games you can play ("I Went To The Market/Zoo," etc). Bring a pack of cards and talk and socialize with the other people in the car. (Bring a plastic bag and some mints in case of puke.) Lastly, plan what you're going to do when you get where you're going.
