It's not a dependence like mental addiction. Your body becomes dependent on it. Your sinuses "rebound" and all but completely block in absence of the spray. I had a cold that blocked my nose up so bad I couldn't sleep because I was afraid of suffocating so I tried one of the sprays and it opens you up like magic, super effective. But about an hour after use if would completely block up again where you literally can't inhale through your nose at all. That's how it is even after you get over the cold/illness. You have to continue to use the spray to keep your airway open until you suffer through breaking the "addiction" by not using it for however long that takes. It really does immediately open your airway, but I won't EVER use it again because it's really scary to be completely blocked like that and have to get a dose in every 30mins-hour just to breath.
