What's more, according to the manual, "Caffeine-Induced Disorders may be characterized by symptoms (e.g., Panic Attacks) that resemble primary mental disorders (e.g., Panic Disorder versus Caffeine-Induced Anxiety Disorder, With Panic Attacks, With Onset During Intoxication)."
The manual also describes "Caffeine Withdrawal" thus: "A characteristic withdrawal syndrome.... Drowsiness, fatigue and mood changes from coffee withdrawal can mimic Amphetamine or Cocaine Withdrawal." Symptoms include "headache," "marked anxiety or depression," "nausea or vomiting" and "worsened cognitive performance (especially on vigilance tasks)." Symptoms "can begin within 12 hours of cessation of caffeine use, peak around 24-40 hours and last up to 1 week."
