Quitting coffee overnight is how people learn what a caffeine withdrawal headache feels like. It arrives on day two, lasts a couple of days, and makes most people give up and go back. The way through is a ladder, not a cliff.
Why bother at all
Not because coffee is bad — it isn't, for most people. But if you're sleeping badly, feeling wired-and-tired by mid-afternoon, or noticing your heart racing after the second cup, stepping down usually fixes more than any herb you could add.
The four-week ladder
Week 1 — move it, don't cut it. Keep the same coffee, but nothing after 2pm. Caffeine's half-life is around five to six hours, which means a 4pm cup is still half-present at bedtime. Most people notice the sleep difference before they've cut a single cup.
Week 2 — swap the last one. Replace your final coffee of the day with green tea. About a third of the caffeine, plus L-theanine, an amino acid that pairs with caffeine to give a steadier kind of alertness — the "focused but not jittery" feeling matcha drinkers talk about.
Week 3 — swap the middle one. Green tea again, or matcha if you want more from it. Keep the morning coffee. This is the week that stalls people, so hold here for two weeks if you need to.
Week 4 — build a caffeine-free afternoon. Tulsi, peppermint or rooibos. Rooibos is the useful one for coffee drinkers because it's dark, full-bodied and takes milk without tasting odd.
Where to stop
Most people don't want zero. One good morning coffee and caffeine-free afternoons is a genuinely comfortable place to land, and it's where the sleep benefit mostly comes from anyway. There's no prize for finishing the ladder.
Try this today: do week one only. Nothing after 2pm, everything else unchanged. It costs you nothing and it's the step that does most of the work.
