The AA Big Book talks about attempting controlled drinking or abstinence for a year for those who are uncertain about their drinking/alcoholism. If you try this and if you are honest with yourself, you will soon know if you have a serious problem.
But perhaps you already know this?
If you are in fact an alcoholic, the drinking path is predictable and it's not good. Alcoholism is progressive in nature. I don't believe that anybody escapes from this fact.
On the other hand, sobriety offers endless possibilities. After 16 months sober, I see absolutely no downside to being a non-drinker. I feel free.
Also, I read one definition of an alcoholic hitting bottom that really stuck with me:
"do you want this to be your bottom or do you want to get hit even harder?"
I'm so grateful that I stopped while I could still make that chioce.
