I use almost this exact line with fatties except change 'then drink' to 'then eat' I don't pretend to understand the alcoholic mind but I remember seeing a documentary where the alcoholic was hallucinating (auditory & visual) in less than 12 hours from not drinking. He was in a concrete cell and trying to dig a hole to get under the bars so he could visit his son. He tore at the concrete till his fingers bled & had to be sedated. His son was dead for close to a decade at this point but he did not realize this. Wicked stuff.
