I'll try really hard not to be judgemental since you came forward, stated your case, and asked for genuine help.
At your age and place (married w/children) I would HIGHLY recommend giving up drinking and the Night Life.
I have seen it destroy MANY sailors while I was in the Navy (married and single). I did the whole clubbing/bar hopping scene for a little while. By the time I was 21 I had grown tired of it.
This will probably make me sound like a judgemental asshole, but I really dont know how it can be entertaining to do the exact same thing every week for years at a time. I dont understand why folks fail to see there is so much more to life. You go into almost any bar in America and talk to the barkeep, he will tell you of at least a handful of guys who have been comming in constantly for years on end, whine about their problems, and never get up and do anything about it.
Since you recognize it isnt the best possible choice you are already well into the road to recovery. I recommend doing something, ANYTHING to relieve your stress that doesnt rely on chemicals, especially alcohol.
Alcohol is THE most dangerous drug in the world. Its legal and easily accessible, and for those reasons alone many people have no problem using and abusing it.
I managed to stop the drinking game long before it became a problem, mostly because I observed all the fine people it ruined. I encourage you to do the same.
