How much coffee do you drink a day? If you’re anything like the majority of U.S. workers who consume the tasty beverage, you knock back at least two cups o’ joe to keep your furnace stoked.

That’s according to a survey of 4,700 professionals, in which 61 percent of respondents who turn to coffee to get through the day say they drink two or more cups.

That’s a lotta lattes—not to mention cappuccinos, black, light and sweet, French roast, espresso, percolated, freeze-dried, and the list goes on and on and on like an over-caffeinated colleague.

Which professions are turning to coffee the most? The study, by CareerBuilder and Dunkin’ Donuts (naturally), ranked the top 15 professionals “who need coffee to get through the daily grind.”

PR/marketing professional is No. 2, and that’s no java jive. (Last year, PR ranked No. 9 among professions.)

Here’s the full list. And, in case you hadn't heard, Sept. 29 is International Coffee Day, so drink up.
