Well, I purchased the sinus flush kit called Neilmed Sinus Rinse kit that Skunky recommended. It has an 8 ounce plastic bottle with a 8 ounce fill line with 50 packets of the flush product. Very easy to use and not at all uncomfortable to use. You flush one side with 4 ounces and then repeat on the other side. Heating 8 ounces of water in a measuring cup in the microwave for 30 seconds gets it lukewarm. I use the recommended distilled water. But you can boil water on the stove. Anyway the Neilmed Sinus Rinse kit cost me $10.99 at Walgreens and does actually seem to be helping some. Had no burning irritation in my nose all last night after using it at 7:00 p.m.! Worth a try for those of you who thought it sounded horrible as I did myself. But it is not bad. Can be used twice a day.
