The answer is, you can't stop drinking because you have developed an addiction to alcohol. When you have an addiction to alcohol, you are no longer calling the shots. Alcohol is the new boss. When you first started drinking, you associated having a few drinks with good times with your friends. But for those of us who have that special alcoholic mechanism in our brain, eventually the good time drinking is going to turn into constant, nightmare drinking. You are in a pattern of literally drinking against your will. The Webster's definition of addiction is: The compulsive need for and use of a habit-forming substance (such as heroin, nicotine, or alcohol) characterized by tolerance and by well-defined physiological symptoms upon withdrawal; broadly: persistent compulsive use of a substance known by the user to be harmful. This very important aspect is the hallmark symptom of addiction - compulsion. You have the mental and physical compulsion to drink, and this compulsion overrides your intellect, reason, self-discipline, and will. You have lost control over the situation. The drinking is now controlling you. Very few alcoholics are able to stop drinking without some kind of help. As anyone with an alcohol addiction knows, even when you rally all of your inner resources and make a genuine and firm decision to stop drinking, it is just a matter of time before you pick up again. Most problem drinkers have tried this very thing many times without success. Addiction is a very real form of bondage.
