I'm not sure if this has been discussed before, but I find this article interesting.

Apparently, research indicates normal rats placed in a cage with an alcohol solution ignored it. Inject thiq in same rats and they went to town on it.
Dormant thiq in the brains of abstaining alcoholics may explain the rate and severity of relapse.
If true, this may answer a whole lot of questions
Keep well
