1 ) Lets See, I'm 52 now. Started probably around 18, right when I went to college. So 30+ years.
2 ) Binger pretty much since then. 2-3 sometimes 4 a week. Didn't really start getting bad until about 5 or 6 years ago when I started keeping hard liquor in the house. Before that I'd actually stop once I caught a buzz, before I'd pass out or fall asleep
3 ) Beer and whiskey earlier, then beer and vodka. The taste of whiskey wore on me.
