One of the coffee roasters nearby me highlighted their decaf single origin and thought to try it on a whim one day. It was so good, I stopped drinking decaf coffee that day and bought three bags of the stuff.

It's been two months since I did this. The biggest benefit I've noticed was feeling how insanely tired I am. Fortunately, I've been working on that problem, but damn, coffee really covers up sleep deprivation well.
