Researchers Roland Griffiths and colleagues documented caffeine dependence and withdrawal in controlled studies published in the Journal of the American Medical Association in 1994. Their work showed that regular caffeine users can develop withdrawal headaches, fatigue, and irritability within hours of abstinence. A 2013 review by Steven E. Meredith and colleagues in the Journal of Caffeine Research summarized diagnostic criteria overlap with other substance use patterns: unsuccessful efforts to cut down, continued use despite harm, and craving. The DSM-5 lists caffeine use disorder as a condition for further study, reflecting clinical interest without full diagnostic code status in every setting.

The Quiz Hub built this am I addicted to caffeine quiz as an original self-report screener inspired by those themes, not a reproduction of any single published instrument. Readers often compare it to sibling tools on this site. Our why am I so tired quiz screens fatigue drivers across sleep and stress rather than stimulant habits. The anxiety test maps persistent worry and tension that can overlap with caffeine jitters but uses a different symptom frame. The am I burnt out quiz measures exhaustion and cynicism over a month, not coffee refills.

Sample item types include frequency ratings such as whether you had a headache when you missed your usual caffeine, or whether you stuck to a daily limit you set for yourself. High compulsive use with high withdrawal symptoms often lands in Mixed or Higher Dependency Signals. Exam season, shift work, or new parenthood can spike scores temporarily.
