You might have difficulty concentrating
Fatigue and irritability are two side effects of a no-coffee diet that also contribute to lack of concentration. Blame it on the lack of stimulants you get from a dose of coffee, as well as the increase in adenosine, that pesky hormone that makes you feel tired. To counteract the loss of concentration, try chewing minty gum to keep your brain alert and on task.
You will feel calmer
Caffeine is a stimulant, meaning it hits your nervous system’s gas pedal. Caffeine triggers a release of adrenaline, needlessly putting you into “fight or flight” mode. Get rid of caffeine, and you’ll feel less anxious.
You might feel sick
Headaches aren’t the only painful symptom of coffee withdrawal. Those who stop consuming coffee have reported side effects like depression, anxiety, dizziness, flu-like symptoms, insomnia, irritability, mood swings, and sluggishness. However, you won’t feel this way forever.
