I'm pretty sure that caffeine doesn't increase most people's productivity.
Any mental performance ascribed to caffeine in studies is always due to removing withdrawal symptoms. It doesn't increase them past their baseline.
In addition, caffeine works by stressing the body, thus reducing creative problem solving capabilities.
So, really if you quit caffeine, your performance might suffer for a few days, then it'd be back up to 100% or even higher.
I don't use caffeine (though I love coffee, it does not love me) I do use smallish dose Adderall XR for my ADHD, but even then I reduce/stop it when I need to be creative (architecture/design of complicated systems). For me, Adderall is great for slamming out repetitive tasks, it reduces my capacity for lateral thinking.
