What is Caffeine Use Disorder?

Caffeine Use Disorder is a pattern of caffeine consumption that leads to dependence, inability to cut down, withdrawal symptoms, and interference with daily functioning. Although not fully listed as a formal disorder in all diagnostic systems, it is recognised by clinicians and researchers due to increasing global caffeine consumption through coffee, tea, soft drinks, chocolate, energy drinks and supplements.

How much caffeine is too much?

• Safe limit for most adults: Up to 400 mg/day (approx. 2–4 cups of coffee)
• High-risk consumption: More than 600 mg/day
• Younger individuals: Much lower tolerance; energy drinks pose high risk

Sensitivity varies. Some individuals experience symptoms even at lower doses.

Signs and Symptoms of Caffeine Use Disorder

• Strong cravings or urge to consume caffeine frequently
• Inability to reduce or stop consumption despite wanting to
• Using caffeine even when it causes anxiety or sleep disturbance
• Needing higher amounts to feel the same level of alertness (tolerance)
• Withdrawal symptoms when caffeine is reduced
• Daily functioning impaired without caffeine

Common Withdrawal Symptoms

• Headache (most common)
• Fatigue and low energy
• Irritability or depressed mood
• Poor concentration
• Nausea or body discomfort
• Sleepiness or lethargy

Symptoms may begin 12–24 hours after stopping and may last up to a week.

Risk Factors

• Long-term heavy caffeine intake
• Using caffeine to cope with stress or low mood

• Insomnia and fragmented sleep
• Increased heart rate and blood pressure
• Gastrointestinal issues (acidity, reflux)

How to Manage and Treat Caffeine Use Disorder

• Use grounding and relaxation techniques to manage cravings

4. Nutrition and Hydration

• Drink at least 2–3 litres of water/day
• Include magnesium-rich foods to reduce headaches
• Use fruit snacks for natural energy

5. When to Seek Professional Help

• Underlying anxiety or panic disorder worsens
• Caffeine impacting work, sleep, or relationships
• Repeated failed attempts to reduce intake

Key Takeaways
