Hi Gato, welcome! Very glad you found us and decided to post. There is a lot of support here, and a lot of great information. Check the sticky posts at the top of the page, and read read read. A useful tool for me at the beginning was 'urge surfing', so I recommend that to you.
The most important piece of info I can give to you is to simply believe that you deserve a life without addiction, and that you will have it, no matter what will happen. It might not be easy at times for you, but so what? It is nothing that you cannot handle, and handle well. Believe in yourself. Visualize the life you will have now that you no longer drink, and then do it!
Onward!
