This final note is for those of you who are seriously wired every morning. If you buy coffee instead of brewing it, the amount of caffeine you get varies, depending on where you go. The website Thrillist did a little investigating. McDonald's had the least caffeine: 9.1 milligrams per ounce. Dunkin' Donuts: In the middle with 12.7 milligrams.

And the terrifyingly-named Deathwish Coffee topped the list: 54.2 milligrams caffeine per ounce. Basically enough to keep you up until October.

Via Thrillist:
