The healthy way to stop drinking

Alcohol withdrawal

Alcohol withdrawal differs significantly from withdrawal from other drugs in that it can be directly fatal. While it is possible for heroin addicts, for instance, to die from other health problems made worse by the strain of withdrawal, an otherwise healthy alcoholic can die from the direct effects of withdrawal if it is not properly managed. Heavy consumption of alcohol reduces the production of GABA, which is a neuroinhibitor. An abrupt stop of alcohol consumption can induce a condition where neither alcohol nor GABA exists in the system in adequate quantities, causing uncontrolled firing of the synapses. This manifests as hallucinations, shakes, convulsions, seizures, and possible heart failure, all of which are collectively referred to as delirium tremens.

Detoxification or 'detox' for alcoholics is an abrupt stop of alcohol drinking coupled with the substitution of drugs that have similar effects to offset the withdrawal symptoms. Benzodiazepines are the most common family of drugs used for this, followed by barbiturates.

Detoxes are performed in multiple ways. The first takes into consideration the varying degrees of tolerance. In it, a standard dose of the benzodiazepine is given every half hour until light sedation is reached. Once a baseline dose is determined, the medication is tapered over the ensuing 3-10 days. Another option is to give a standard dose of benzodiazepine based on history and adjust based on withdrawal phenomenon. A third option is to defer treatment until symptoms occur, which is safe only with relatively mild alcohol users

I think too

You need to stop it gradually so that your system doent get abrupt side effects

It depends on how much of an alcoholic he/she is.  If they are getting blind drunk or falling down drunk every day, they need to be under a doctor's care, because for those people, stopping suddenly can be fatal (ever hear of the D.T.'s?).  If someone is trying to cut down to nothing, they must do it slowly, or the same problem will result.  However, a true alcoholic will probably not be able to stop on his own; after 24-36 hours, he will be craving a drink so badly, that nothing will stop him from getting one.  For a true and realistic depiction of what will happen, rent  and watch the movie "The Days of Wine and Roses", with Jack Lemmon and Lee Remick. 

In essence, there is no "healthy" way to stop.   The only prudent way is under medical supervision (e.g., a detoxification/rehabilitation Center).  There's one in every major city; even in Israel.

For firs prevention alcoholic must stop drinking at once (I'm AA), then best is to go to therapeutyst or doctor. Hard keyses of stop drinking must be solved with some medications. Best cure is support of all your family and friends to stop drinking.
