If the biggest thing you want out of your coffee in the morning is “oh my God, wake me the heck up please” . . . a new study figured out where you should buy it.

Buzzfeed bought 24 cups of coffee from four different major national chains:  Starbucks, 7-Eleven, McDonald’s, and Dunkin’ Donuts.  Then they had a lab analyze the cups to figure out every chain’s average caffeine.

And the most jacked up coffee is from 7-Eleven. Their cups had an average of 280 milligrams of caffeine. But, since we don’t have a 7-Eleven in Topeka (you will find one in Holton)

Starbucks was second at 267 milligrams . . . McDonald’s has 227 milligrams . . . and Dunkin’ Donuts has 220 milligrams.

After Buzzfeed got the results, they asked people if they’d consider switching to 7-Eleven now that they know it’s got the most caffeine and 14% said yes, they’re planning on switching.
