Scram, like others have said, the mental aspect in quitting is huge. I had to completely take drinking off of the table. There was / is no place for alcohol in my life today. Each time I left a tiny opening, I would fail...
Until I completely got any option to drink out of my head, i had lost before I began to fight.
I also spent as much time on SR as I could early on. It does get easier with time, but in the beginning I spent a ton of time here... read old posts and try to be active posting as well.
There is no blue print for sobriety, what works for me might not work for you. The common goal, however, is you have to want to be sober and don't drink today.
When you feel yourself start to get weak, log into SR and post for help. Do anything to ride out that craving; trust me it will go away.
You do have the power to make this change for good and you won't regret the decision!
