When someone becomes a drunk, treating the problem should be the same as treating a regular disease - a chronic regular disease. You admit then into hospital, prescribe medication, and make sure that they take it. Only this time, the hospital is a rehab facility, or an alcohol treatment center, and the medication is... abstinence.
A lot of guys in rehab have physical dependence on alcohol. This occurs when they are so uncomfortable without the substance that they could get physical with you when you get in their way. Sometimes they hurt those who are around them; they never mean it that way, but still they do it, and they should not be encouraged.
When you have a history of addiction to liquor in your family tree, you know you can easily catch the habit yourself. Once you find you have begun to take liking for the substance, it might be a good time to seek professional help, like, say, an alcohol treatment center.
Alcohol is a friend when you celebrate, but a mean foe when it gets out of control. The way to beat it is with help from pros who know what to do and how to assist you. You find then in alcohol treatment centers within you vicinity.
Once you have been through alcohol treatment, you are strongly forbidden from ever again touching the stuff. The simple argument is that you'd never be able to control it. Some people debunk this theory by actually doing it, but many others fail and catapult back to alcohol treatment.
Hypnotism is one option that people are reluctant to explore for curing alcoholism. However, a few alcohol treatment centers press on with the theory and there are reported cases of it working. It might still take a while though, before the practice gains widespread acceptance.
You don't have to be a drunk to be in rehab. You might be something worse, like an addict to crack or some other narcotic; or you could be better, just a person who needs a change of environment and wanted to be somewhere different.
