When this check is useful

If the usual amount no longer wakes you up and the cups have multiplied, if skipping coffee brings a heavy head or headache, or if you keep drinking it late in the afternoon knowing it will cost you sleep, it is time to take stock. This check looks at the constructs studied in caffeine use disorder research over the past month: tolerance and withdrawal signs, continued use despite knowing the downsides, and failed attempts to cut back.

It is particularly useful for office workers and students drinking three or four cups or more a day, people running on energy drinks at night, anyone with frequent palpitations, hand tremor, or stomach upset, and those with insomnia or anxiety who find caffeine hard to cut. The items were developed independently by Soundary with reference to published literature; they are not a translation or adaptation of any standardized scale, and the tool is a reference screen that has not yet been clinically validated. The score bands are provisional, based on symptom frequency.

What to do with your result

Dependence and withdrawal signs (items 1-4) and daily-life impact and control problems (items 5-8) are each scored 0-12: 0-3 is almost none, 4-6 mild signs, 7-9 a level that deserves attention, and 10-12 a clear possibility. In the mild range, logging your daily total, moving caffeine into the morning, and setting the last cup at least eight hours before bed can already change your sleep. At 7 or above, taper by one cup a day over one to two weeks rather than quitting abruptly, which eases withdrawal headaches.

Caffeine that will not come down often sits on top of sleep deprivation, fatigue, or anxiety. If either area is 10 or above, or repeated attempts to cut back keep failing while palpitations and insomnia continue, work out a plan with a psychiatrist or family physician. Recheck after four weeks to compare, and read it together with sleep, fatigue, and anxiety self-checks to judge whether caffeine is the cause or the consequence.

How scores are interpreted

Dependence and Withdrawal Signs

This is the sum of scores from items 1 to 4 (0-12 points), looking at how frequent tolerance signs (increased intake) and withdrawal signs (headaches, irritability, sluggishness when skipping caffeine) were. A higher score may mean your body has become accustomed to caffeine. The range boundaries are provisional criteria based on symptom frequency logic and are for reference only.

0–3pts · Minimal Signs of Dependence
Over the past month, there were almost no signs that could be considered tolerance or withdrawal. Keep maintaining your current comfortable amount and timing. (Provisional criteria)
4–6pts · Mild Signs of Dependence
It seems you occasionally increased your intake or felt heavy-headed and sluggish on days you skipped. Making small adjustments, such as tracking your daily total and keeping your intake mostly to the morning, can be helpful. (Provisional criteria)
7–9pts · Signs of Dependence Requiring Attention
You may be experiencing frequent headaches and irritability when skipping caffeine, along with an increasing need for it. Rather than quitting abruptly, slowly cutting down by one cup a day over 1 to 2 weeks can ease withdrawal discomfort. If the discomfort continues, you may want to consult a professional. (Provisional criteria)
10–12pts · Probable Distinct Signs of Dependence
Your tolerance and withdrawal signs may be occurring almost daily. Since caffeine is intertwined with sleep, anxiety, and heart rhythms, it can be difficult to manage on your own. We recommend consulting a professional, such as a psychiatrist or family medicine doctor. This result is a reference screening result, not a diagnosis. (Provisional criteria)

Impact on Daily Life and Difficulty Controlling Use

This is the sum of scores from items 5 to 8 (0-12 points), looking at whether use continues despite knowing it causes discomfort like sleep disruption or palpitations, and whether attempts to cut down are unsuccessful. A higher score may mean caffeine is placing a significant burden on your daily life and body. The range boundaries are provisional criteria and are for reference only.

0–3pts · Minimal Impact on Daily Life
Caffeine is not placing a major burden on your sleep or condition, and you are managing it well on your own. Comfortably continue your current habits. (Provisional criteria)
4–6pts · Mild Impact on Daily Life
It seems late-day caffeine occasionally pushed back your sleep or left you with palpitations. Simply setting a cutoff time for your last cup at 8 hours before bedtime can make a difference in your sleep quality. (Provisional criteria)
7–9pts · Impact on Daily Life Requiring Attention
You may be continuing to use caffeine despite knowing the discomfort, and finding it hard to cut down. Since a lack of sleep, fatigue, or anxiety often underlies the inability to reduce caffeine, please look into those areas as well, and consider consulting a professional if the difficulties persist. (Provisional criteria)
10–12pts · Probable Distinct Impact on Daily Life
You may be in a state where control is difficult despite clear signals from your sleep and body. Since this pattern easily fuels insomnia and anxiety, we recommend making a plan to cut down with a professional, such as a psychiatrist. This result is a reference screening result, not a diagnosis. (Provisional criteria)

FAQ

How do I interpret my caffeine dependence score?

You answer 8 items on a 0-3 scale, and two areas are scored 0-12 each: dependence and withdrawal signs (items 1-4) and daily-life impact and control problems (items 5-8). Read 0-3 as almost none, 4-6 as mild signs, 7-9 as deserving attention, and 10-12 as a clear possibility. The bands are provisional thresholds based on symptom frequency, not a diagnosis.

How much caffeine a day is too much?

For healthy adults, up to about 400 mg a day is the commonly cited ceiling, roughly three or four cups of brewed coffee at 75-150 mg each. During pregnancy or with anxiety, insomnia, or heart rhythm problems the limit should be much lower. Note that this check measures signs such as tolerance, withdrawal, and failed control rather than intake itself, so a modest amount with clear signs can still score high.

What are caffeine withdrawal symptoms and how long do they last?

Headache, drowsiness and fatigue, poor concentration, irritability or low mood, and occasionally nausea are the typical symptoms. They usually begin 12-24 hours after the last dose, peak on day one or two, and settle within about a week. Tapering by one cup a day over one to two weeks is far easier than stopping abruptly. If headaches are severe or prolonged, see a doctor to rule out other causes.

Does this diagnose caffeine use disorder, and when should I seek help?

No. This is a reference screening tool developed by Soundary, and caffeine use disorder itself is still a research concept, so any diagnosis rests on a professional interview. If either area scores 10 or more, or repeated attempts to cut back fail while insomnia, palpitations, or anxiety persist, it is worth making a plan with a psychiatrist or family physician.
