Ever wonder why it's so common that some alcoholics would try about anything at all to drink like a normal person?
It's often called the desperate experiment.
There are email mailing lists available to sign up and observe bad drunks trying hard to moderate and manage their drinking. They alternate between soaring determination and deep confusion when they again fail, having no idea why success in something so simple as just having a few now and then without getting drunk and sick is unavailable to them. It really is pretty terrible.
Glad it's not encouraged here on SR.
