You can drink a lot when alone.
In a cursory survey [1] of the alcoholics I've known (both recovering/acknowledged and not), for 80% social drinking hasn't been the problem. The problem was what they did when they were alone with a bottle.
[1] Not an SRS, clearly anecdotal and entirely in my head, so all caveats apply, etc.
Used to do the same thing with gaming. Encrypted windows and whensend.com the key to me in the future. Can't game on the linux drive.
