3 Must-haves inside the car to stay awake. No, it doesn't include obligatory conversation.
1. Coffee drink aren't always available. Your best resort is chocolate-covered espresso beans.
By the way, Meiji Coffeebeat doesn't have caffeine. Yea, I thought so too.
2. OxyCan. Oxygen in a can. Park, breathe in & viola! you'll feel rested instantly. Like you just woke up.
3. Spicy snacks. It should be hot enough to keep you awake & not scream for water.
