My caffeine experiment is almost at its end. For the past week, I have only drunk decaffeinated coffee. One funny thing I noticed is that decaf coffee is not nearly as disappointing when you are no longer addicted to caffeine.

My caffeine free (or almost free) lifestyle thus far has left me with no downsides: my energy level is just fine all day. I am not tired at all during work hours, and I no longer desperately crave an afternoon coffee each day. I do fall asleep earlier at night and more easily, which is a benefit. Instead of not being able to sleep until 2 A.M. most nights, I am ready to turn in by midnight, and sometimes even earlier, which puts me more in sync with my wife.

All in all, after a rocky start with three days of withdrawal symptoms, my experiment has been a success.
