As long as we're giving decongestant advice, in my experience a neti pot (sinus rinse) really helps.

I also take pseudoephedrine when things get bad. I'm not trying to push a natural stuff only approach.

The neti pot really seems to reduce the odds that sinus congestion will spiral into a terrible sinus headache.

Do be aware of the need to use sterilized water to avoid a possible dangerous infection, though. Distilled water is the easiest way.
