KatieDid, I get from your post that you are already perfectly clear on ever drinking again, You know what happens when you drink, and that will never change. For me, the possibility of drinking in any reasonable manner again vanished many years ago, it was never going to happen.
There will always be that voice inside that says, 'You know what's fun? Alcohol!'. Always. I needed to find a way to accept that and realize that the voice no longer comes from me, and that I do not do what it says any longer. The voice has no power over me.
Congratulations on your sobriety, and on your upcoming wedding. It will be beautiful, I'm sure it will, and it will be because you now know that you have the power inside you to make it that way, and you choose to be sober.
