Quick answer

Energy drink withdrawal is mostly caffeine withdrawal. Symptoms usually start 12 to 24 hours after your last can, peak around days 1 to 2, and fade within 2 to 9 days. Headache, tiredness, low mood and trouble focusing are most common. The FDA says about 400 mg of caffeine a day is an amount not generally associated with negative effects for most adults; if you’re drinking several cans, add up the caffeine on the labels.

Symptoms, phase by phase

The caffeine withdrawal symptoms confirmed by research (Juliano and Griffiths, 2004) include headache, fatigue, decreased energy and alertness, drowsiness, depressed mood, difficulty concentrating, irritability and feeling foggy, and sometimes flu-like symptoms, nausea or muscle pain. Energy drinks can be high in sugar too, so some people also notice cravings; see our sugar withdrawal timeline. The FDA notes that medical experts advise against energy drinks for children and teens because of their sugar and caffeine levels.

Onset: 12 to 24 hours after your last energy drink

  • Headache starting
  • Tiredness, low energy
  • Less alert

Peak: About 20 to 51 hours (day 1 to 2)

  • Headache
  • Fatigue, drowsiness
  • Low mood, irritability
  • Trouble concentrating
  • Sometimes nausea or muscle aches

Easing: Day 3 to day 9

  • Symptoms fade day by day

What makes withdrawal longer or shorter

  • Total daily caffeine. Juliano and Griffiths found symptoms got more common or severe as the daily dose rose, and stopping doses as low as 100 mg a day caused symptoms. Several cans plus coffee or pre-workout adds up quickly. Check labels.
  • Cold turkey vs tapering. The FDA advises cutting back gradually.

When to see a doctor or get help now

  • A sudden severe headache, or one with fever, stiff neck, confusion or weakness: get urgent care.
  • Chest pain, a racing or irregular heartbeat, or fainting at any point: get urgent care.
  • Symptoms that last beyond about 9 days.

Tapering

Cut back gradually, for example one can fewer every few days, or switch to a smaller or lower-caffeine drink before stopping. The FDA says that if you want to cut back, it’s best to do so gradually.

Tips for getting through it

  • Taper over a week or two
  • Swap one can for water, sparkling water or decaf tea
  • Prioritize sleep while you cut back
  • Read labels: many energy drinks list caffeine per can

Frequently asked questions

How long does energy drink withdrawal last?

Usually 2 to 9 days, with the worst on days 1 to 2.

How much caffeine is in an energy drink?

Is energy drink withdrawal dangerous?

Usually not, but a sudden severe headache or heart symptoms need urgent care.
