Timeline and Symptoms of Caffeine Withdrawal

Caffeine is hands-down the most widely consumed and unregulated psychoactive drug. For years, the term addiction was used sparingly when referring to caffeine and was only used when referring to the likes of cocaine and heroin. However, an increasing body of research is finding links between continued caffeine consumption and a number of health problems, including addiction (Meredith et al., 2013).

Development of Caffeine Addiction

Adenosine is a chemical element produced in body cells. In the brain, adenosine works as a central nervous system depressant that helps your body wind down in preparation for sleep. When consumed, caffeine binds to adenosine receptors in the brain and confers the opposite effect. It makes cells excited and blocks any adenosine from being absorbed, which makes you more alert. This is why many Americans depend on their morning cup of coffee to start the day. 

It is also the same reason why people become dependent on caffeine when frequently taken in high amounts. With prolonged use, the brain tries to counter the effect of excessive adenosine in circulation by developing more adenosine receptors. This results in tolerance, which requires you to take more coffee or other caffeinated beverages progressively to achieve the same level alertness.


Any time you stop taking your daily dose of caffeinated beverage, the brain’s delicate chemical balance is disrupted. There are far too many adenosine receptors that are left unoccupied and not nearly enough adenosine molecules floating around to attach to these receptors.

The brain manifests this disruption through a number of withdrawal symptoms that usually appear within 24 hours. The timeline of events often follows this pattern after your last caffeinated beverage:

First 12 – 36 hours

People often get irritable, anxious, fatigued, and sleepy without their morning cup of coffee. However, as the day progresses, more symptoms might show, including poor concentration, brain fog, reduced motivation, and headaches.

20 – 48 hours

During this period, symptoms are often at their peak. You might experience intense headaches, vomiting, nausea, muscle aches, cold and hot spells, impaired cognition and motor skills, and depression. These might come and go throughout the 48-hour window.

48 hours – 1 week

The worst part of the withdrawals should be over by this time, though some people can experience symptoms for up to 2 weeks.

It is important to note that the intensity and duration of caffeine withdrawal symptoms will often depend on a number of factors. These include:

– Your age and weight

– Gender – women break down caffeine slower than men

– Duration of caffeine use and amount of caffeine used

– Individual biology – genes, individual health

– Pre-existing conditions that affect the liver

– Whether you are on other medications or you are smoking

These factors might shorten or lengthen your caffeine withdrawal timeline, so make appropriate adjustments when planning to come off caffeine.

Managing Caffeine Withdrawal

If you have been a heavy caffeine user, you might want to use a slow taper to get off caffeine. Consider cutting consumption by 15% every week while replacing this percentage with decaf, green tea, or other healthier substitutes. Get lots of rest, keep yourself hydrated, eat healthy food, and stay fit for an all-round healthy existence when you finally drop the caffeine habit.

If you need support during the withdrawal process, Caffeine Support can come in handy during those tough times. This is a natural supplement containing the right balance of vitamins and minerals designed to maximize the benefits of caffeine while helping you get off caffeine. Caffeine Support helps boost concentration, wakefulness, and alertness even without caffeine, which helps you stay focused and counter the effects of caffeine withdrawals.
