How much caffeine is safe?

Up to 400 mg per day for most adults — about four 8oz coffees. Pregnancy limits are 200 mg. Sensitivity is genetic; some people get anxious or sleepless from a single espresso.

Follow-up questions

When should I stop drinking coffee?

8–10 hours before bed. Caffeine's half-life is roughly 5–6 hours.

Can I get addicted?

Dependent, not addicted in the clinical sense. Skipping causes real withdrawal headaches for 2–3 days.
