How the Symptoms Occur

Caffeine is the most widely consumed psychoactive substance in the world. This stimulant blocks adenosine receptors and decreases drowsiness. The neurotransmitter adenosine regulates the sleep-wake process of the body. As these receptors get blocked, you experience a temporary feeling of alertness and wakefulness.

Caffeine also boosts adrenaline, dopamine, and other neurotransmitters and hormones, and reduces the flow of blood to the brain. And when your brain functions without caffeine, you start experiencing withdrawal symptoms. The good news is caffeine withdrawals do not last very long.

Caffeine Withdrawal Symptoms

The intensity of withdrawal symptoms will be proportionate to the caffeine you consume every day. Common symptoms include headaches, tiredness, and mood changes. 


Caffeine withdrawal symptoms are mostly characterized by headaches. The stimulant reduces the blood vessels of the brain, leading to a constricted blood flow in the cerebral region.

And when you stop consuming caffeine, the vessels expand, leading to a higher blood flow. You experience headaches as the brain tries to adjust to this change. The withdrawal headaches go away when the brain manages to adapt to the change. 

How long do caffeine withdrawals last, particularly the headaches? The severity and duration of the headaches vary from person to person. In most cases, the duration does not exceed 7 days.

Another common symptom of caffeine withdrawal is fatigue. Caffeine blocks adenosine receptors, which leads to reduced drowsiness and improved energy. In some circumstances adenosine causes fatigue. And when caffeine is eliminated from your system, you are likely to feel fatigued and tired.

Fatigue and boredom can be frustrating. But fatigue can help your brain’s neurotransmitters to settle down, and in the long run that can lead to more sustainable energy. Your bloodstream quickly absorbs caffeine and your body excretes it through urine.

As you consume more coffee, tolerance increases, making you dependent on caffeine. The more dependent you are on the substance the worse the withdrawal symptoms will be. But how long do caffeine withdrawals last, particularly this feeling of tiredness? Well, depending on your level of addiction and your metabolism, this feeling can last for up to a week.

Mood Changes

Caffeine withdrawal is also associated with anxiety, depressed mood, and difficulty concentrating. You may experience all these feelings together as your body craves caffeine.
