Don't know if any of you have ever heard of the Neti Pot (think that's how you spell it). I saw it on Dr. Oz last year and bought one. It comes in a kit and has packets of saline rinse in. It rinses out our sinuses and help prevent the mucous from going into your chest. Everything starts in the nose so it really makes sense. At the sign of a cold I use it right away and have really kept down those nasty colds. I usually get bronchitis at least once a year and have not had it for the last two years. My husband didn't believe it until he got a really bad cold last month. He didn't use it until the cold got really bad. Well when he did use it, he couldn't believe how it cleaned out his sinuses and he was actually able to breathe normally. You can buy them at most drug stores. Good luck!!!
