I can't quit it. When I do, after about 2 weeks I completely lose the ability to be a good worker bee and sit in my open plan office,and hide my contempt for the absolute rank ineptitude of almost everyone else there. Load me up with the happy brown juice and I can pretty much make it through. I'm not convinced this is sustainable tbh.
Chesterton called it, quite fittingly, "The Puritan's opium".

Caffeine in Floral Nectar Enhances a Pollinator's Memory of Reward - https://www.science.org/doi/10.1126/science.1228806
> Caffeine improves memory in humans, millions of whom find that their daily dose enhances clarity, focus, and alertness. The human relationship with caffeine is relatively recent, however, and thus its impact on our brains is likely a by-product of its true ecological role. Caffeine occurs naturally in the floral nectar of Coffea and Citrus plants. Wright et al. (p. 1202; see the Perspective by Chittka and Peng) found that caffeine presented at naturalistic levels significantly improved the ability of bees to remember and locate a learned floral scent and potentiated the responses of neurons involved in olfactory learning and memory.
PBS Eons Why Does Caffeine Exist? (5:13 for the bit on bees) - https://www.youtube.com/watch?v=PzshAqowsyI
> In experiments on bees, researchers have found that once they've had a sip of caffeine-laced nectar, it boosts their memory, makes them preferentially revisit the plants, and even helps them pollinate faster and more efficiently. So, for plants, caffeine is a multi-purpose molecule with a lot of adaptive benefits. But, for us, it has one main benefit: it gets us through Monday morning. ...
