It may be the only step you need, SarahLou. This is a huge decision you are making, a death defying choice. You are so worth this, and you deserve a life without addiction and the misery that comes with alcoholism.
What are you going to do instead of drink? Making a plan is an excellent idea. Picture yourself doing what sober folks do, and then go do that.
You can decide to quit, and then.....QUIT DRINKING! For good! YOU can do this, YOU can succeed. I have a feeling you will too!
