ummmm... actually, Mmaarrkk (hope I got all those letters in there)
Anyone I drank with in butte (which is most of the population - I was a bartender here) will tell you that I *am* allergic to beer.
I drank vodka.
If I drank beer, before half way in ... my nose would close up, my eyes and hands would swell... and I'd be nauseaus for all the next day.
Not that that would STOP me, mind you, if that's all there was; but it was quite real.
