titcr. I had most of the sinuses in my face removed surgically, because I had so many sinus infections that it became medically necessary. I can practically breathe mud now. There is no force of nature that will ever clog up my shit again. It's a bitch, hurts like hell, costs a ton of money and you may not be able to eat for two weeks, but it's totally worth it.
It's the kind that goes up one nostril and out the other while you stand over a sink. Similar to waterboarding yourself, but it totally clears the sinuses. Worth it.
But it totally works. I spent years breathing out of one nostril or the other, but never both at the same time. After that surgery and using those pots I feel like I'm in an oxygen enriched environment.
