Same for me. I spent the first 45 years of my life breathing almost entirely though my mouth. Then I tried some nasal spray that was great, but made the situation worse when I inevitably overused it, so I went to a doctor. I had been told when I was a kid that I had polyps, so I went to see about getting them removed. She put me on Flonase, which at the time was prescription, and since then I've been able to breathe through my nose unless I'm sick. It has been a significant quality of life improvement for me.

Gentleman, here we have the prototypical mouthbreather! Took him almost half a century to discover nasal sprays!

I’ve taken it for over 30 years now. It has indeed been a lifesaver and so much better than all the pills. One side effect is blurred vision and I have definitely noticed a slight blurring in the last couple of years. I gladly accept it as a small price to pay for decades of relief.

I feel like this is a trade-off not always understood and accepted in modern times; we expect our medicines to be perfect and our bodies to be restored to new condition, and when this isn't the case we feel betrayed.

Moving to the coast made me feel like I finally woke up, after growing up perpetually stuffy and sniffly. Turns out I'm not a mouth breather after all!

Yep - moving away from the coast basically did the opposite for me. :(

Just moving away from what your body decided to be allergic to when you were a kid with a bored immune system seems to help a lot, I moved from the Gulf Coast to the West Coast and my allergies receded a lot. I eventually moved back to where I grew up and they didn't really return except on days when the whole city's collective nose is running because all the trees are having an orgy up in there.

I have had bad allergies for a lot of my life. I probably have some sort of histamine intolerance behind it all.

Recently my allergist gave me a tip with regard to nasal congestion. First, you can use Flonase and Astepro together, apparently they work better when used together. Astepro has an antihistamine in it that can help. Second, moisturize the interior of your nasal passages with a drop of muciprocin in each nostril applied inside your nose at the tip of it, then squeeze your nose gently to distribute. This lets you use get the benefits of Flonase without drying out your nose (which can trigger congestion).
