We Love Coffee Too Much to Stop at 2 PM:

We built this because we love an afternoon coffee ritual but hate what it does to sleep: Caffeine has an average half-life of five hours. A late-afternoon cup remains active in your system well into the evening, physically blocking your brain's adenosine receptors.

Clinical sleep trials demonstrate that consuming caffeine even six hours before bed significantly fragments the deep, restorative sleep cycles your body needs to recover. We wanted a way to enforce a strict 2:00 PM caffeine cut-off without giving up coffee.
