Rob: just one thing, you say: "If things do get out of control, I am pretty confident that I will address them."
I tend to think that you are thinking about this in the wrong way. Just because things don't "get out of control" doesn't mean there isn't any problem that should be addressed--"functional" is a relative term as well. And even if it does "hit the fan" at some point, there is no guaruntee that you will find recovery--this is a progressive deal. It sounds to me like you are justifying your behavior, saying that you are playing Russian Roulette with only one bullet in the revolver, while the rest of the alcoholics are doing it with two, three, or four bullets. Why play the game at all?
