I've been using the Saline Rinse by Neil Med for about 6 1/2 months now. My Dr. told me to stop using the small spray bottle from Walmart and get this because it does a better job. My pharmacy also has a an extra strong one and for the life of me I can't remember the exact name but it is by NeilMed also.
My sinus infections have been reduced by more than 80% and my sense of smell is beginning to come back.
REMEMBER: when using this saline rinse use DISTILLED WATER or you may feel a rush of burning just like when you are swimming. Believe me I know as I ran out of DW and tried tap and darn near drowned myself. Ugh!!! The thing is you have to tilt your head to the side slightly and chin down a bit over the sink. SO far I have not caught DH's bad cold (like the ones everyone is describing here) that he has had a week and a half. He quit using his saline wash. Too much trouble he said.
Lots of good advice here. Just pray I don't get sick.
