Well, to be completely honest... It might be. In fact, studies have shown that drinking coffee even six hours before going to bed will make it significantly more difficult to fall sleep. Once you do fall asleep, you won't sleep for as long or as deeply as if you drank, say, a glass of milk instead. Bummer, right?
If you drink coffee and are having sleep problems, coffee may very well be the culprit.Journal of Clinical Sleep Medicine
Of course, a glass of milk doesn't have the complexity, smooth mouth or rich flavor of a well-brewed cup of coffee. The first sip won't make your heart flutter like you just came back from a promising first date, and it won't empower you to accomplish superhuman feats like building a website about drinking coffee. And who needs sleep, anyway? Pfft. It's not like it contains caffeine or anything.
So go on. Go brew that cup of coffee. You deserve it.
