I need it a little during the spring when the weather changes. I'm careful not to over use it (every 2 days tops) and don't have problems if I stick to that. If I use it too often it makes my sinuses a little raw.

Sometimes while in Texas I had to resort to kenalog shots in the nose (also a steroid) just to be able to cope with allergies down there.

I'll have to look into the quercetin.
