Yes snorting it almost always hurt like hell for me, but a few times (I've had HCl and HBr salts) especially from pills it was really quite fine. But yeah forget about those few lucky times, I almost always regretted the mule kick and only did it again after forgetting how bad it was, a few times - especially when caustic drip lingering screwed up the trip too long.
While the short onset and intensity aren't that bad themselves to have experienced, it's hardly worth it and you are so much better off just dosing high orally. I recommend against snorting.. Me forgetting was just stupid and stubborn.
I hardly if ever regretted plugging it, but always with enough water to dissolve! Probably don't make a habit of it, but I think I'd rather plug with water solution than destroy my nose so much more. Plugging only gave me kind of a warm feeling iirc - not a particularly pleasant type of warm, more like a mild version of spicy food. Then again spicy food doesn't actually irritate membranes so much, mostly confuses your heat sensitive neurons (though yes when extreme enough they can get so confused that you get a reaction as if actually burnt.
