Clarity: Caffeine and Focus

The UK's productivity culture is built on caffeine. But almost nobody understands how it actually works. We know caffeine blocks adenosine. We know it has a half-life. But we don't track when we drink it. We don't see how much is still active at bedtime. We don't connect poor sleep to yesterday's 4pm coffee. The result? A culture of perpetual fatigue, masked by more caffeine, creating worse sleep, requiring even more caffeine. It's a loop. And it's invisible. Clarity exists to break that loop—not by drinking less, but by drinking deliberately. We're building a tool to change the UK's relationship with caffeine. Because timing matters more than quantity. And awareness is the first step to control.
