OP I've been reading a lot lately about why some people are alcoholics and some not. When I read the following, it was like a lightbulb went on in my head...
"By way of a review, let me describe what the Big Book says about Step One and what differentiates an alcoholic physically, mentally, and spiritually, from a non-alcoholic. Physically, the alcoholic has an allergy, or an abnormal reaction, to alcohol. This abnormal reaction to alcohol is a craving for more alcohol once we take a few drinks. This craving NEVER happens to a non-alcoholic. Because of this, a non-alcoholic can ALWAYS predict how much they are going to drink, but an alcoholic CANNOT. Besides the craving, alcohol DOES something for an alcoholic that it does NOT do for a non-alcoholic. When an alcoholic drinks, they get a feeling of ease and comfort; an "IN control, get up and go into town, I like this" kind of a feeling. When a NON-alcoholic drinks, they get an "OUT of control, beginning of a nauseating, slightly tipsy, I don't like this so I don't want any more" kind of a feeling. That's why they stop after one or two, and make statements like, "I don't want another drink because I am feeling that first one." Spiritually, because of the selfish and self-centered way the alcoholic views and deals with other people, their emotions, and life; they are filled with inner turmoil, discomfort, and anxiety. Since alcohol is the ONLY thing that we have experienced, which brings relief from this inner unmanageability, we turn to alcohol again and again, even though it has caused problems for us in the past. We don't see what alcohol is doing TO us, we ONLY think about what it is going to do FOR us, which describes the alcoholic's mental obsession. A NON-alcoholic's relationship with alcohol is a "take it or leave it" kind of relationship, but an ALCOHOLIC'S relationship with alcohol is a "I need it to deal with life" kind of relationship. Please ask yourself if you can relate to the experience of an alcoholic.
The following is an explanation of what happens when alcoholics put alcohol into their bodies, and how it is a completely different experience compared to non-alcoholics. No wonder why non-alcoholics can't relate, and make statements like, "Can't you just stop after one or two drinks?" It shows why alcoholics can use their willpower against everything EXCEPT alcohol.
Alcoholics make up about 12% of the population. The body of the alcoholic is physically different than the body of someone who is not an alcoholic. The liver and pancreas of the alcoholic process alcohol at one-third to one-tenth the rate of a normal pancreas and liver. As alcohol enters the body, it breaks down into its various components, one of which is acetate. We know now that acetate triggers a craving for more acetate. In a normal drinker, the acetate moves quickly through the system and exits. But that doesn't happen in an alcoholic. In alcoholics, the acetate of the first drink is barely processed out, so by staying in their body, it triggers a craving for more acetate. The alcoholic then has a second drink, now adding to most of the acetate of the first drink, and that makes them want a drink twice as much as the normal drinker. So they have another. Then, having almost three times the craving as a normal drinker, they have another. You can see from that point how alcoholics have no control over how much they drink. The craving cycle has begun and they have no choice but to keep drinking. Once the acetate accumulates in their body, and that begins to happen with only ONE drink, they will crave another. And how many times does an alcoholic think it would be nice to have JUST ONE drink to relax, but has many more? Now you see why. AND THIS CAN NEVER CHANGE!
On top of THAT (like it's not bad enough already), alcohol is a poison because it destroys human tissue. The two organs that alcohol damages the most are the liver and the pancreas. So the more the alcoholic drinks as time passes (or doesn't drink, because the liver and pancreas also deteriorate naturally as we age), the less their body is able to processes the acetate. THAT is why alcoholism is a progressive, fatal illness. The Big Book says on page 30, "We are convinced to a man that alcoholics of our type are in the grip of a progressive illness. Over any considerable period we get worse, NEVER better." Pretty revealing, huh. It explains many things I never before understood"
Hope this makes sense to you too. You're not weak, but the combination of having the type of physiology that processes alcohol a certain way, plus other psychological/ circumstantial factors means that you ( we) are at greater risk of developing the condition and can't moderate alcohol.
