I have heard people in AA sharing that they use to mark the bottle with a pen. But as they kept drinking, they will lower the mark few inches lower but eventually they will just ignore it and promise themselves they will strictly follow the rule the next day. They will repeat the exercise and fail. I didn't do that kind of chores. But once I remember, a friend had given me a bottle of Chivas Regal (1 liter bottle). I polished it of in 2 days. I was embarrassed when he checked to see if I still had it, I had to lie that I and my brother cleaned it up. After coming into the fellowship, I realized certain segment of the people cannot control the amount of liquor they consume once they put an amount of liquor in their body. That explained the fact that I could never plan the amount of beer or hard liquor I will consume, always fell short, only to tell my self that I should plan well.
