Hi Paulos,
different people react differently - I was just like you, I had to stop smoking and drinking at the same time. The two were so linked together for me, I just knew it had to be like that. I've "slipped" a couple of times with the smoking since then, and every time, suddenly my drinking-sobriety has felt a hell of a lot less solid.
And as for the rest - agree with Tazman. It can really help to do this with others. It's like training for a sports event - it's a lonely road if you have to do it all alone. "Campaign" is a tricky word - a lot of people have found that if you think about sobriety as a fight, or a war, it can make it more difficult.
Maybe it's like playing golf - be focussed and determined, but relaxed... Another sports analogy! Don't know where they're all coming from.
Good luck, and keep posting!
