How much caffeine is in your day? A budget builder with a bedtime check

How much caffeine is in your day? Typical amounts for espresso, filter coffee, tea, cola and energy drinks, set against the European Food Safety Authority's guides: up to 400 mg a day for healthy adults, 200 mg in a single dose, and 200 mg a day in pregnancy.

Add up your own drinks with the builder, then see roughly how much is left in your system at bedtime.
