I tried the undilted urine using an eyedropper into the old nose last night - laid on my back and used a massage vibrator thing on my face. Got some snot out but not as much as I hoped. Still feeling sinus pressure this morning.
I ordered a Grossan Hydro Pulse Nasal & Sinus Irrigation System with Grossan Sinus Tip and can't wait til it arrives.
I also bought a can of saline spray - easier to use at work than trying to snort salt water out of a cup in the women's bathroom.
