Interestingly, many prescribe naltrexone along with abstinence, and say the drug should be taken every day. In clinical trials when taken this way it is shown to be no better than a placebo, but in trials when taken as per The Sinclair Method (ie, pill only taken an hour before drinking) it is shown to be far more effective. Here's some links to some studied - http://www.c3foundationeurope.org/clinical-trial-evidence/
People undergoing The Sinclair Method often find there are two parts to their addiction - the chemical part, and the habitual part. Sometimes once the chemical part is extinguished they also have the habitual part to stop.
The habit/chemistry dichotomy is also part of giving up cigarettes.
There are questionnaires you can take to reveal how much your addiction is chemical led e.g. do you smoke first thing in the morning (when the chemical levels are low) or do you smoke as part of some routine.

What levels of effectiveness is that. Placebo's are reported as being pretty strong medicine: no better than placebo is pretty good if your placebo is effective in 40% of cases for example.
