Avocado, you mention that you see alcoholism as the result of some bad choices, and that you are confident in your ability to make the right ones. I might be in the minority here, but I fully agree with you. The bad choices in this instance led to a full blown addiction for me, but that is me.
You will stay sober if and only if the choices you will make about drinking are simply that you will never drink again, no matter what, and you will never change your mind. Choosing to have 'just one' would lead right straight to hell for me. Be well and best to you.
