Something with Dayquil - it has other medicines that do work for pain and cough suppression. Depending on your symptoms, those two can work and make you feel better even though you're not getting any real decongestion benefits. That makes it harder to detect that the decongestion part isn't working. That is, of course, until you're introduced to the stuff that really does work and then wonder how you went so long without it.
