Strong black tea is my drug of choice. But I got fed up with caffeine addiction a few years back and started to limit my intake. Currently I’m at 1.5 litres every second day, which means that my system is used to going without caffeine for over 40 hours at a time — counted from afternoon tea on a Monday to morning tea on a Wednesday for instance. This regimen works out to an average daily intake of 190 milligrams of caffeine. Coffee has about 1.7 times the caffeine in strong black tea, which in turn has 2.7 times the caffeine in Coke. But I never have coffee and very rarely any caffeinated soda.
Dear Reader, what’s your caffeine habit like? Here are some figures:
Coke: ~100 mg caffeine per litre
Strong black tea: ~250 mg caffeine per litre
Coffee: ~425 mg caffeine per litre
(A litre is about 34.5 fluid ounces.)
