Have you thought of you being an alcoholic? Only alcoholics have that what we call in AA, the phenomenon of craving that happens after we put the 1st drink in our body. We cannot just stop with one, we always end up drinking more than we originally planned for. But thats not the only problem of an alcoholic. He/she would make several promises not to drink that day or for a week or for a month, but the obsession would kick in and end up taking that 1st drink. And off to the races.
