Well tubbs, sorry if I was tugging the whistle on my own meth train at every intersection, I didn't realize you were getting anxious over urges. Unless you meant cravings for a different drug, in which case let me know and I'll hook up the pneumatics.
I did the math based on a paper's math (linked somewhere): A fifth of liquor/day ~ 8 bars of Xanax in seizure and anxiety risk. Alcoholics will dissolve their esophagus at some point, tolerance can't go up forever; but I don't know where the upper benzo limit is. Even without one, I don't think any drunk has used a full liter of liquor just to "calm his nerves" before an interview.
