DIY Nasal Saline Rinse Solution

I hab a cold (said in most pitiful of voices). I always seem to have colds or some sort of congestion between being around kids, and having sinuses that are chronically swollen. People have been telling me for years about how much I need to do nasal rinses, and while I did them sporadically, I've only recently started to do them regularly.  I'm sick of being sick, and  if they help keep me from getting horrible sinus infections that are having to be treated monthly with antibiotics, I'm willing to shoot pressurized water up my nose.

For the record they AREN'T sinus rinses. You do NOT rinse your sinuses, but rather your nasal passages. If we could rinse our sinuses we would get mondo infections because anything we inhaled could get in them.  This little disclaimer was brought to you by my old ENT who got verrry annoyed when people talked about how wonderful sinus rinses were.
