Vicks Sinex 12시간 코 스프레이 - 0.5 oz.

Woke up completely stuffed up this morning and this spray cleared me out within a minute—the 12-hour relief actually held all day, which is a game-changer for sleeping through the night.

The spray works fast and the 12-hour relief is real—I only needed one dose before bed and slept through the night. Downside is the nozzle drips a bit if you tilt your head too far, but it's a minor issue for how clear my sinuses feel.
