I had to get one Tuesday. I took a sick day (where I stayed in bed all day instead of getting stuff done around the house like I thought I could). Well after having to go into work for the past two days I took today off too (another 12 hr sleep night). I got out the Neti Pot (which hadn't been working too well, the left side was so clogged the water wouldn't drain through) and after being persistent with it I finally got it working. I think I went through 10 tissues through this. But hey, I can actually breathe through my nose right now! I guess they do work when you can actually get the water flowing!
So- Have you tried it? What do you think of the neti pot?
