While this might come off as a bit sanctimonious, I'm thankful that I no longer drink like I did in my youth and can wake up early the day after Cinco de Mayo, on a Saturday no less and enjoy my morning / day without a splitting headache and hangover that would have been guaranteed a decade ago. I still went out and had a great time, just without the sauce. Not drinking on Cinco de Mayo, St. Patrick's day, etc. would have been sacrilege pre-2010.
