If you can't get by without your morning cup of coffee, you aren't alone.

A new survey finds many professionals feel more productive at work when they drink coffee.

Food preparation and service workers top the list of those needing a caffeine boost. They are followed by scientists, sales reps, marketing and public relations professionals and nurses.

Dunkin' Donuts and CareerBuilder commissioned the survey as part of this Saturday's "National Coffee Day."
