Most of us get up in the morning, have one huge caffeine fix and think we're ready to start the day. Studies have shown there is actually more benefit to be had from sipping caffeinated drinks every few hours than simply first thing in the morning. And we actually don't need the large amount most of us think we need.
A moderate amount of coffee or tea consumed throughout the day will provide more energy bursts and improved alertness than a Venti on our way to work.
