I started irrigating my sinuses after i had my first surgery when I was 14, im now 19. Let me tell ya, it works great. When I first started I had to mix it all up and use one of those booger-suckers for babies to squirt it. Now I've found this Sinus Rinse Kit from NeilMed, it comes with little pre-mixed packs of the solution, all you do is add water, and a bottle that you mix it all in and use to rinse. It definitely helps me alot in the morning when Im feeling congested. I also havent had to get as many sinus surgeries done, only about 3, because it kept them clear...or maybe im just lucky with my sinus'.
