Neti Pot

[Ponyup]

Okay, now I'm curious. I've done some research on line & it doesn't seem as gross or expensive as I once thought. So who has used one? How difficult is it to use really? Do you feel like you're drowning? I almost drowned when I was 3 so this is a big one for me, I can't even put my face in the shower because I can't breathe. If this were to happen with the pot I would probably panic & choke to death.
Do you buy the salt mixes advertised or just use regular salt? Where did you buy yours?
