Ok, hear me out here.
Nyquil is Nyquil, not “Nightquil,” so why is it called Dayquil instead of “Dyquil?” It would fit so much better if you could have Nyquil and Dyquil. How cool would that be huh!? Either that or change Nyquil to Nightquil, which wouldn’t be so cool. What do you say people, should we get an angry mob together or what!?
