Quite a few years back, as a young lad, I was fishing groundfish longline off Nova Scotia with a salty Icelandic fisherman.

I was hung over. He offered me "snuff" he instructed to be sniffed up deep and later blown out on a hankie. He wagered it would cure my hangover. Begods, it worked and my mind was clear, well at least for the day. Next day I had the woest headache ever, and a sinus infection to boot. That really got up my nose.
