That’s why if you developed a dependence you don’t quit cold turkey.
The strategy I’ve heard is purchasing a normal bottle, and refilling it with boiled cool water when it’s ½ empty. Then refilling it again when it’s ¾ empty.
Xylometazoline is an absolute godsend, and has even more efficacy in a dual-action spray with saline water.
It feels nothing short of magical to do one spray per nostril, and be completely uncontested in less than 10 minutes.
In my experience oxymetazoline has similar fast-action - even "10 minutes" seems a bit on the long side.
