Seems like a "drink this in a bind so I can still function stash" thing tbh. Last bad beer drunk I knew was a bassist that couldn't play steady until he had six beers. After that he was rock solid. Then when he hit 9 beers it all fell apart again on his way to guzzling the whole case. I had to cut him loose and he was just like "why, man?" Was my first real experience with an alcoholic in a band setting so at the time I was scratching my head thinking he's clueless. Last time I ran into him was at a party where he was drinking beer and just out of the blue vomited, sat back up, and proceeded to sip his beer as though nothing had happened.
