Up to 400 milligrams (mg) of caffeine a day appears to be safe for most healthy adults. That's roughly the amount of caffeine in four cups of brewed coffee, 10 cans of cola or two "energy shot" drinks. Keep in mind that the actual caffeine content in beverages varies widely, especially among energy drinks.

I'd say on average I drink around 5 standard coffee mugs or around 60 oz of black coffee each day. Work has a pretty good drip coffee maker, so I typically drink three mugs in the morning and two in the afternoon. 1 to 3 10oz cups. Cut out the cream and sugar and you'll be much better!

Coffee itself won't instantly make you feel tired, but the caffeine it contains may actually lead to fatigue after regularly drinking it over time. If you stick to 400 mg of caffeine per day or less and go easy on the added sugar, you should reap the benefits of caffeine and avoid its drawbacks.
