For me it was just fixing alcohol. Or changing that habit. I am not saying I am perfect or have no problems but none of them need addressing for me to stop drinking and being happy. My biggest problem now is having to go to work tomorrow, which is a good problem really. Like you said, we are all different. Some go to alcohol because of problems, some have alcohol create problems. I had some problems because of alcohol but none that were long term. Just in the moment problems. For me it was my fault. Alcohol was not to blame, I just drank to much of it. Now that I dont drink my life is basically the same except I feel better, have no, or very little, anxiety, and have alot more cash at hand. Drinking is a wonderful habit to give up.
