Stopping after a long time of boozing is extremely hard.
One bit of simple advice.
Stay out of the fucking pub. If you're not going there with a bunch of guys for a night out, there is no reason to be there.
I used to drink up to 1/2 bottle of vodka a night and these things worked for me.
Just plain stopping i almost impossible at first.
On your way home, buy a 4 pack or a six pack, then don't buy any more, that's your limit for that night. Only ever buy booze in quantities that you can finish in one night. Pour all your hard spirits, vodka etc. down the sink. No good will come of them.
Other techniques I used were substitution. Whenever I had that urge for alcohol, I would make a cup of tea, or eat a yogurt.
Boredom is threat to all alcoholics. You have to find something to do. Golf in the summer. Sounds stupid, but it worked for Alice Cooper. He took up golf to give himself something to do to stay away from alchohol.
Xbox, TV, porn are simple. Walks, gym, stay at work longer. Join something. Do something else other than sitting at home.
Alcoholism and stopping are somewhat linked to depression.
Even going to the docs for some short term depression meds will help you achieve all the above.
Good luck.
You'll need it.
The only other help you get is when you do something so insanely stupid when you are drunk that your recovery will be court ordered or you fuck up your body so bad, some doctor will scare the living shit out of you.
I know its harsh, but sadly its true.
Seriously, good luck, but the only person who can really help is you.
