Can you tell the differences between the box on the right and the box on the left? Allow me to point them out ...

• The box on the left says “Daytime” in the light blue box at the top, while the box on the right says “Nighttime” in that place.
• The box on the left says “Non-Drowsy Day Time” in yellow print above the large, dominant “Cold Head Congestion” copy, while the box on the right says “Night Time” there.
• The box on the right lists “Antihistamine” as one of the uses in the dark blue box under the large, dominant “Cold Head Congestion” copy, where the box on the left does not.
• The “cool ice caplets” in the image on the box on the left are white, while they are blue in the image on the box on the left.
• The contents of the box on the right will knock you the fuck out, while the contents of the box on the right will not.

As you may have gathered, I didn't notice these differences until after I woke up from my five hour nap.
