Has Daylight Saving Time messed with your bedtime? Or perhaps the tumbling stock market has you tossing and turning past lights-out. Or maybe, just maybe, you can't sleep because of that "decaf" you ordered at dinner.
A long-standing debate among the caffeine-wary is whether decaf served in restaurants is actually what it's billed to be—or is really a cup of the high-octane stuff? Are you among the wide-eyed skeptics? Read on.
Do-it-yourself caffeine detectors called D+caf Test Strips will tell you if your beverage is—or isn't—the real thing. Just stick one of the tiny strips into a spoonful of coffee or tea (sans any milk or sugar, which eliminates drinks like lattes and sodas) and you'll have your answer in less than a minute, according to Discover Testing, which makes the strips. If the line above "D" (decaf) on the strip is darker, you're good to go; if it's darker above the "C" (caffeine), beware—your drink probably contains more caf than you'd like.
