Method and limits

The caffeine figure comes from bigelowtea.com; recipes, brewing and batches vary, so a real serving can differ. Bedtime numbers elsewhere on this site use a standard one-compartment model with an average 5-hour half-life and a sleep-friendly line of 50 mg; your own body may clear caffeine faster or slower.
