The good thing about not drinking caffeine is not having to depend on the stuff to wake up in the morning. Another good thing is that when you really need a good dose of high octane (like for a long-distance drive) it keeps you wide awake when you need it. But that's a double-edged sword.
When you're not used to drinking caffeine and you get yourself a triple shot latte on the road, not only does it keep you alert for the drive but it keeps you awake for hours and hours on end after you've arrived.
Maybe I should have gone for a single shot latte.
