Addiction Resource claims that 100 million Americans consume at least one cup of coffee each day. They also report that it’s possible to become dependent on caffeine after using it consistently for only a week or two. Many will find it necessary to give up caffeine due to health reasons, or because their dependency causes unwanted side effects.
Within a few hours after giving up caffeine, you may experience fatigue and have difficulty concentrating. Within 72 hours or so, you may notice headaches that begin at the back of your eyes and move toward the front of your head. Other symptoms may be:
Not everyone will experience the same effects when withdrawing from caffeine, nor will they overcome their addition in the same timeframe.

If you find yourself relying on caffeine to make it through the day (or often use caffeine as a preworkout), it’s possible you have a caffeine addiction. Knowing what to expect when you give up caffeine can make weaning yourself off this stimulant a much easier process should you decide it is necessary to do so.
