I’ve done full nasal saline irrigation when I’ve had a head cold for a long time, more than a decade now. Bought one of the powered rinse things, not just a Neto pot or equivalent. I am a big believer in that use.
What do you do daily? A spray, or a full rinse? If a spray, what are you using, specifically?
This is similar to the machine I have.

I use a NeilMed squeeze bottle.
