Run a 2-week caffeine-free anxiety audit

Remove caffeine entirely for two weeks to establish your true anxiety baseline.

Why it works

When caffeine is a daily constant, it becomes invisible to self-monitoring: you cannot distinguish your baseline arousal from caffeine-elevated arousal. A full washout period (at least 2 weeks to allow receptor normalization) creates a clean comparison point, making the actual contribution of caffeine to your symptom burden legible.

How to do it

1. Taper down over 1–2 weeks first (see the tapering practice) to minimize withdrawal symptoms.
2. Go fully caffeine-free for 14 days, including tea, chocolate, and cola.
3. Rate anxiety, sleep quality, and energy each morning on a simple 1–5 scale.
4. After 14 days, reintroduce a moderate dose and compare scores over the following week.

Evidence

This is a structured self-experiment protocol. The underlying logic — that you cannot detect a constant stimulus — is well established in psychophysics and placebo research. (mechanistic)

Self-report rating scales are vulnerable to expectancy effects; for a cleaner read, keep the rater blind to the comparison they are doing.

Common mistake

Running the audit during an unusually calm or unusually stressful period, which confounds the measurement with life circumstance rather than caffeine.
