See, that's what I thought, and how I'd always heard it pronounced in Colorado. But everyone I've run into here pronounces it koozie, and there are disparate spellings on the inter-webs. Maybe the confusion comes from the idea of a "cozy" keeping something warm... I personally don't give a shit how it's spelled...it's a galdurnd foam tube fer chrissakes.
Though its not directly in keeping with your craft beer theme, don't forget your various shandies, micheladas, and cervazas preparada. Perhaps the stronger flavor of a well-brewed craft beers stands up better to such treatment.
Back when I drank beer (a lot, I must confess) I found it helpful to take a couple of aspirin before I crashed. Also, if you stay up till closing time, going somewhere and having breakfast before you retire, seemed to help. Also, drink a lot of water before you crash. IMHO
