I can only tell you that beating the thing called "alcoholism" is to decide to stop drinking. That's it. My father after many years did it, one day, just like that. No one belived him. He's over 60 now and enjoys alcohol in very normal way. My friend, also 31, quit drinking completely 3-4 years ago and he was a person who drunk unbelievable amounts, even to me, just crazy. Now because of health problems he's 100% sober and he's fine! He's happy and can enjoy everything he was doing before.
So. People will tell you that it is a disease, that you are sick and you won't be able to quit on your own.. Wrong. It's only about you, your decision, your life. Take care and ask yourself some hard questions. Self-awareness and self-acceptance is the key.
