Packing mix up at Proctor & Gamble??

Ok, so I'm convinced that the people at Proctor and Gamble were not paying attention the day they packaged the box of DayQuil I bought last week. Non-drowsy formula, indeed. I took two of those and all I wanted to do was sleep. That same evening I took two NightQuil gel caps and had a horrid time trying to get to sleep.
