Aruba, all I can add is that for me, my consumption was progressive. I started outa weekend drinker and moved on to every day. At first, it was 5-6 beers M-T but pretty soon a 6 pack just didn't cut it. Monday night football, heck everybody does it. And ah why not have some more, I don't work that hard on Friday anyway. Little hangover won't hurt. I used any excuse to drink anytime.
If you can hold steady at a couple beers and always quit, I say more power to you. It's easy for somebody that can't seem to handle it, like me, to blame the alcohol but the truth is it was ME that couldn't stop. I have no one else to blame because most people can stop after one or two or even refrain fro the first. IMO, there is nothing wrong with having a few beers, the problem is when you can't stop yourself from having a few more, and a few more, and a few more...and oh crap, it's 20 minutes until the mrs. will be calling me to bed, better down a couple more...THAT was me.
