I tend to drink more during business dinners. A couple of glasses of wine and maybe 1 cocktail is the norm.
At home, a good glass of red wine from time to time. Beer? I bought a case (you can only buy beer by the case in PA) before the Super Bowl. I have consumed maybe 7 or 8 beers from this case.
There was a time in my 20's and 30's where I could hang all night with co-workers at conventions or seminars and get totally blitzed. I would then bounce back easily for an 8 AM meeting.
Alas, those days are over. Now if I overindulge, I feel like crap until noon. So, I just don't do it.
