Sinu-what?

I just got over a sinus infection. In fact, I took my last antibiotic on February 8th. Obviously, the z-pack didn't do jack because here I am a little more than a week later and I feel something coming on. Could it be my sinuses again? Is it possible that the antibiotics didn't do their job. Possibly. Am I going to spend another $20 on a copay just to get a prescription for some $20 antibiotics again? Probably not.

After talking with my parents tonight, they suggested that I:

1. Keep my cats out of the house -- um, this is not an option and, as far as I know, I am not allergic to cats.
2. Use a warm compress on my face for 20 minutes three times a day -- again, probably not going to happen because I'm not THAT disciplined (besides, I'd look like a jackass at the office when I'm sitting at my desk with a washcloth over my face)
3. Start using a neti pot -- a neti what?

The third suggestion intrigues me. My parents told me that they found some product at Costco today for sinus relief. SinusAid, SinusIde...I couldn't quite make it out and my father wasn't too sure about the exact name. My guess is this:

I figure it's worth a shot -- well, at least that is what my brief rundown of the website tells me. Of course, this warrants yet another trip to freakin' Wally World. Ugh. But, if it means my sinuses get bathed and pampered then I guess it would be worth it, right? I'm a bit skeeved out about intentionally pouring water in one nostril only to see it come out of the other one, but I guess I'll get over it, right?

Anyone out there have any experiences with neti pots or sinus cleansing? Anyone have any other ideas besides asking for yet another prescription (because I'm not good at remembering to take medication)?

I just want to be able to breathe again.
