What kind of sprays - Afrin type (oxymetazoline)? The dependency on those can be pretty awful. My ENT prescribed Azelastine, an antihistamine nasal spray that has worked wonders for me. It appears to raise the threshold for allergic reactions which can include swelling of the nasal passages. I knew I needed it in the Spring but I've found that if I don't use it daily I snore really badly, so I think that general house dust is causing some trouble. My wife is much happier now that I'm using it again.
