Well, what exactly do you want to know? I use mine when I have a cold or allergy issues, and it really does work wonders. It's neat and gross how much stuff comes out sometimes! And even if it doesn't seem like a lot comes out, it just feels good afterwards. It's really not all that messy. I've found that it helps to sniff (lightly) after I'm done pouring on one side. It seems to help loosen the gunk up before I give my nose a good blow. I also warm the water a bit. Mine came with little packets of solution, but you can make your own out of a mix of baking soda and salt. I'm not sure of the ratios, but I'm sure a quick google search will find it.
Status: Remission since late May 2009!
Symptoms began in November 2008, ~4 weeks after giving birth to my son.
Eased for ~3 weeks in December, possibly b/c of probiotic use?
Returned in January 2009 (with a vengeance), diagnosed with pancolitis on January 30.
Currently taking Asacol (400mg 4 pills 3x daily), Rowasa twice weekly, Culturelle probiotic, and Zoloft (25 mg).
