OI - Interesting questions you've posed here. Gotta say, right up front, that this stuff can get involved, so if you want to PM me, feel free.
I quit drinking completely in June of 1988. A DUI was the catalyst for me, along with something else that happened in the neighborhood. I live in a beach town. Have for decades. Back when we were all alot younger (I'm 58 now), we all surfed together, and hung out and partied together alot too. There was a crew of about 25 or 30 guys who all knew each other and one day, somebody asked me if I'd heard what had just happened to this guy Donnie, who was one of the crew.
Donnie had been up in Cocoa Beach partying, wandered across the centerline on his way home, and killed some people. I heard that the sheriffs woke him up the next morning in his cell and asked him if he knew why he was there. He didn't, and they told him. Hearing about this, right after I'd been arrested for a DUI, smacked me right in the face with a reality punch. Here's the thing: all of the guys that I talked with about the Donnie situation agreed that Donnie never got any more blasted than the rest of us did. But there he was, with this awful thing he'd done hanging over him for the rest of his life. The realization that, because he couldn't control himself, innocent people were dead.
I'd been fooling around with the idea of quitting drinking for a month - just to see how I'd feel - when this stuff was happening. As the end of that first month rolled around, and I felt so darn good, I just said "the heck with it," and quit for good. I figured that even if I was involved in an accident in the future, it sure as heck wouldn't be because I couldn't control myself. That was my decision.
Here's an interesting irony, and similarity to your situation: my main thing was beer back then, good beer. Don't be fooled, you can get blind drunk on beer. When I did drink liquor I usually chose rum. Hey, that's what the pirates drank, right ?
Blaine was on the money when he said that if you're asking yourself these questions you might have already answered them too.
Here's something to chew on, and if you want I'm open to talking more. I started to view the drinking thing as a weakness, years ago. This does NOT apply to those folks who can go out and just have a beer, maybe two, and that's the end of it. BUT, there are those of us - I include myself here - who sometimes went out, intending to just get a nice little buzz, and ended up getting pretty well hammered. Maybe you've been able to not get sloppy, as you've noted, but when you drink more than you really wanted to, it's a problem.
One last thing to chew on (hey, you've got so much to chew on here that you won't be able to drink for at least a few days !

).
Here's what I'm talking about: you and I both, and probably a few of the other guys here too, have been dealing with being either unemployed or under-employed for a while. This stuff messes with you; it's almost impossible for it not to.
I don't think that quitting drinking is a "silver bullet" for all of our problems, but one thing that I can say from my past experience over the 23 years since I quit : most problems are aggravated when you're drinking, and those problems won't get that clear thinking that you might need to really solve them. Since I quit drinking I've had most of the foul stuff of life come my way and I managed to not fall completely apart. I've lost jobs, lost girlfriends, had a cancer eleven years ago and my "sweetheart" run for the hills because she "couldn't handle" what was happening to me, lost my Mom, took care of my Dad after, and then lost Dad fairly recently. These things are awful, but they don't get any better by being polluted.
OI, here's a little bit of good news for you. One of my big fears when I quit drinking was that I wouldn't be funny any more. I'm sure that sounds really goofy to some people, but I was always the guy cutting up and doing everything I could to see that people were laughing. Well, it took me a while to realize it, but I was maybe even funnier when I quit drinking. I can go to a party, or out on the town, and I don't have a problem with being the first person out on the dance floor (that's cause I do a wicked Funky Chicken), and I am still blessed with a pretty darn good sense of humor. Maybe not Blaine-funny, but then that kind of funny only comes to earth about once every 20 years or so.
One thing that I learned about myself when I was quitting, and I've tried to use it my advantage. As you may know, they take a different tack with DUI offenders these days than they used to a while back. They used to just show people films of awful car wrecks and hope that would put the fear of God in them. When I was arrested, and they include alot of these deals that you must attend as part of your punishment, I sat through a discussion where the guy hosting the talk was a former mega-drunk, who'd cleaned up his act, gotten a counselor's license, and here he was holding this discussion. He focused on getting us all to look at why it was that we drank to excess, at least enough that we'd come to the attention of the criminal justice system.
I came to realize that I had a bit of the old obsessive-compulsive thing going on. Not as bad as Jack Nicholson in "As Good as It Gets," but I definitely had some of this in me. So I tried to channel this. Instead of being a really good partier, I finally got myself certified to scuba dive. I'd done this for a years in a half butt fashion, but when I was arrested I decided I was going to do something really good for myself to offset the hammering I was going to take from the system. This ended up being a great thing for me. For many years I had adventures that most people can only dream of. Now that I'm older with a banged up knee I can't afford to fix (unemployed, and non-insured when I was), I've gotten the same way with my shooting. I LOVE cooking up loads for the pistols and chronographing them, making notes of all this stuff, and of course, shooting more than I can afford to. So maybe, if you're entertaining quitting, you can "substitute" some really pleasurable activites for yourself, to channel the time and energy in a good way.
Hey, this stuff can get a little involved. I hope you get what you're searching for here. If you want to talk about this some, I'm open. - DixieBoy
