Stock up on Chewing Gum

Even if you're not a fan of chewing gum, stocking up on this stuff for your road trip is a must. Not only can chewing gum keep your breath smelling fresh after a long drive, but did you know that chewing gum can also settle your stomach when driving down a bumpy highway or driving up hills? Because of this, we'd recommend stopping off at the next gas station and grabbing a few packets.
