Hello, I Have Been Using Oxymetazoline Nasal Sprays For Nearly

Hello, I have been using oxymetazoline nasal sprays for nearly ten years now. I have tried to stop using them but can't go a day without them. Is there some sort of salt water rinse I can get? The reason I ask is because I once very nearly died after drowning in the sea and noticed that for the next six months or so I did not need my nasal spray at all! This was the only good thing to take from the whole experience. Please reply. Thanks. Stuart
