2 Months post revision rhino. How do I stop using Afrin?

For the first time I was prescribed Afrin after my revision rhino. I didn’t know it was humanly possible to breathe that well. Also didn’t know it was dangerous to keep using/habit forming...now I’m addicted. I cannot go to bed without one spray in each nostril. How do I wean myself off the sauce without being a mouth breather? When I stop use my nose closes completely! Can I replace with a different product that works just as well, but is safe? These OTC sprays do nothing so far.
