Key Takeaways
- Caffeine withdrawal usually brings a headache, fatigue and sleepiness, a low mood, irritability and trouble concentrating, and some people also feel nauseated or achy.
- Symptoms typically begin within about a day of the last cup, are strongest over the first day or two, and fade within a week or so.
- Most daily coffee drinkers are physically dependent on caffeine to some degree, which is the body’s normal adjustment to a daily chemical, not an addiction.
- Stopping all at once is what makes the first days so unpleasant, and stepping down gradually over a couple of weeks avoids most of the crash.
- Smaller cups, half-caffeinated blends, an earlier last cup and dropping one serving at a time all work.
- Tea, energy drinks, chocolate and some pain relievers count toward the daily total.
- Caffeine and other stimulants can increase anxiety and trigger or magnify symptoms during a benzodiazepine taper, so many patients reduce it slowly, with their doctor aware of the change.
Caffeine withdrawal feels like a headache with fatigue, a low mood and a foggy head, starting within about a day of your last cup and easing within a week. The way to avoid most of it is to taper, cutting your daily caffeine a little at a time over a couple of weeks instead of stopping on a Monday.
What are the symptoms of caffeine withdrawal?
The headache is the most common symptom. It is a diffuse ache, often throbbing, that builds gradually, and it does not respond well to being ignored. Along with it comes a tiredness that feels out of proportion to the day you have had.
While the headache gets the attention, the fatigue is what most people remember. Then the mood goes. People describe feeling flat, irritable and short with the people around them, and ordinary tasks take more concentration than they should.
Of course, not everyone gets the full picture. Some feel nauseated, and some notice aching muscles, as if a mild flu were starting, while others get the headache and nothing else. In fact, many people have had the whole syndrome on a Saturday without knowing what it was: they sleep in, skip the coffee they would have had at work, and spend the afternoon blaming the weather.
Nobody has ever been admitted to a 28-day program for drinking coffee. Yet, what the body is doing on that Saturday afternoon is the same thing, in miniature, that it does when any drug it has adjusted to is taken away. So, when does it begin, and how long does it go on?
When does it start, and how long does it last?
Caffeine withdrawal typically begins within about a day of the last dose. For a person who drinks coffee every morning, that means the next morning, often before they are fully awake. The first symptom arrives at the hour they would normally be fixing it, which is one reason so few people recognize it for what it is.
The worst of it usually falls over the first day or two. After that, most people feel the headache loosen and the fog thin, and within a week or so the whole picture has usually passed. A few people describe a longer tail of tiredness, measured in days rather than weeks.
Unfortunately, there is no reliable way to tell in advance how hard your own stop will be. How much you drink, how long you have drunk it, and how your body handles caffeine all play a part, and none of them can be read off a label. What can be said is that the picture is short-lived, and that it is a nuisance rather than a danger.
While a bad week is not dangerous, it is enough to send most people back to the coffee pot by Wednesday. That is the real reason tapering matters. Nobody is asking you to prove that you can suffer through it, and the point is simply to get where you are going.
Why does caffeine cause withdrawal at all?
Caffeine is a stimulant. Taken every day, it pushes the brain toward alertness, and the brain, which does not like being pushed, adjusts to push back. After weeks or months of daily coffee the two pushes cancel out, and the cup that once woke you up now mostly returns you to normal.
That adjustment is physical dependence. It is not an addiction. Dependence is what the body does with many of the chemicals it receives every day, and it happens to steady, sensible people who have never craved anything in their lives. Addiction is a pattern of behavior around a drug, and most coffee drinkers have nothing of the kind.
An analogy that might help is to imagine standing in a river. If the current runs past you all day, every day, you learn to lean upstream without thinking about it. The lean is your adjustment, and it keeps you upright for as long as the current flows.
Now imagine the river stops one morning. You do not stand up straight. You fall, upstream, because the lean is still there and nothing is pushing against it. The headache, the fatigue and the low mood are that fall. While this is not a perfect analogy, it shows that the problem is not the missing coffee but the body’s lean, and that the lean takes time to unlearn.
Fortunately, there is another way out of the river. You can wade toward the bank, where the current weakens a little with each step, and straighten up a little at a time. Nobody falls over that way. Step toward the bank, and do not wait for the river to stop.
How do you taper off coffee without the crash?
The principle that governs a medication taper governs coffee too: make each reduction small enough that your body barely notices it, and give it time to settle before the next. In practice, that means stepping down over a couple of weeks rather than quitting between Sunday night and Monday morning. While the exact schedule matters less than the shape, the shape matters a great deal.
There are several ways to make a step smaller. You can pour a smaller cup, you can switch part of the pot to a half-caffeinated blend, or you can drop one serving at a time, starting with the one you would miss least. Moving your last cup of the day earlier is a step too, and it often improves sleep before it does anything else.
Keep in mind that coffee is not the only source. Tea, energy drinks, cola, chocolate and some over-the-counter pain relievers all carry caffeine, and a person who gives up coffee while reaching for an energy drink has not tapered anything. Count the whole day, not just the mug.
If a step brings the headache back, you have learned something about your own pace, and nothing has gone wrong. Hold where you are for a few more days, or make the next step smaller, and then carry on. Your body sets the pace here, not the calendar.
Why does caffeine matter during a benzodiazepine taper?
While caffeine is the everyday example of withdrawal, and a useful one because everybody has felt it, it is a small example. A person coming off a benzodiazepine such as Xanax (alprazolam), Klonopin (clonazepam) or Ativan (lorazepam) is dealing with a nervous system that has adjusted far more deeply, over years rather than weeks. The symptoms of benzodiazepine withdrawal are in a different league from a coffee headache.
There is also a direct connection. Caffeine and other stimulants can increase anxiety and trigger or magnify symptoms during a benzodiazepine taper. So, many patients choose to reduce their caffeine while they taper, and the question of cutting caffeine during a benzo taper has its own article.
The way to reduce it is the way described above: slowly, one serving at a time, with your doctor aware of the change. If you change your coffee and your benzodiazepine dose in the same week, neither you nor your doctor can tell which change caused which symptom. One change at a time keeps the picture clear.
The lesson also runs the other way. Nobody would tell a daily coffee drinker that the headache is all in their head, or that the cure is to quit faster. Yet, people on benzodiazepines are told both things all the time, and tapering benzos too fast is one of the most common ways a taper goes wrong.
A benzodiazepine taper typically takes a year to 18 months or longer, and a benzodiazepine is never stopped abruptly, because an abrupt stop can cause seizures. If you think someone is having a seizure or another medical emergency, call 911, and for a mental health crisis call or text 988.
Frequently asked questions
Can caffeine withdrawal cause a headache for days?
Yes. The headache is the most common symptom, and for some people it lasts several days before it eases. It typically fades within a week or so of the last dose. A headache that goes on well past that, or that is severe or unlike any you have had before, is a reason to see your doctor rather than to assume it is the coffee.
Is decaf completely caffeine free?
No. Decaffeinated coffee carries a small amount of caffeine, far less than regular coffee but not zero. For most people the trace does not matter, and moving some of the day’s coffee to decaf is a reasonable step in a taper. Someone who is very sensitive to caffeine may notice it.
Can you taper with tea instead of coffee?
Yes, for many people. A cup of tea usually carries less caffeine than a cup of coffee, so swapping some coffee for tea makes the step smaller. Tea still counts toward the day’s total, so it is a step on the way down and not the end of the taper. An energy drink is usually not a step down at all, and a large can may carry more caffeine than the coffee it replaces.
Does caffeine withdrawal cause anxiety?
Caffeine itself is the more reliable source of anxiety. Withdrawal usually runs the other way, toward tiredness and a flat mood, though some people feel irritable and on edge in the first day or two, and a poor night’s sleep adds to it. New or severe anxiety during a caffeine taper deserves a conversation with your doctor, especially for anyone who is also tapering a medication.
Should you quit caffeine before a benzodiazepine taper?
That is a decision to make with your doctor, and there is no rule that fits everyone. What is settled is that caffeine, like other stimulants, can increase anxiety and set off or magnify symptoms while you taper a benzodiazepine, which is why many patients choose to cut back.
If you do, cut back slowly, and try not to make the change in the same week as a dose reduction, so that each change can be judged on its own. Your doctor can help you to decide the order.
This is the principle Dr. Leeds’ practice is built on. Patients taper benzodiazepines and z-drugs under medical supervision, at a pace the patient directs, with weekly video visits often up to an hour and 24/7 text access for urgent questions, and the plan adjusts to what the patient reports rather than to a preset schedule. The thinking that gets a person off coffee without a crash, applied carefully and over a much longer time, is the thinking that gets a person off a benzodiazepine.
