Using a nasal rinse daily, even when not experiencing congestion, does wonders. I don't use a NetiPot but it's the same thing.. Just a bottle that you squirt up one nostril and out the other with warm water and a packet of saline treatment stuff. I have pretty much chronic sinus infections, as does my brother, he got sinus surgery and it hardly even helped. On a side note, sinus surgery is such a shitty operation. It's so nasty when they have to take out the packing they fill your sinuses with and it has scabbed over in their so they basically yank out tampons from each nostril that are stuck to the inside walls of your sinuses.
