SoberLife, I don't know that its "will power". For me, its more like dealing with a rain shower: I can't willfully make it stop raining, but I can carry an umbrella to deal with it.
My Dr. was very helpful. It was a relief to admit my problem. My daughter lived with me at the time and having someone here to physically watch me and make sure I didn't drink got me on the road to sobriety. It was me who stayed there but I don't think I'd have gotten through those first two nights if I'd been alone.
SR has helped me stay sober. I read so many posts and think "me too!". Seeing how others deal with the guilt and repercussions of bad decisions while drunk is very comforting and has helped as well.
Don't get defeated and don't give up.
