Hardly ever, because I'm surrounded by alcoholics. When I don't drink, that makes them feel guilty, so they don't get quite so sloshed.
But when they aren't around, I'll drink until I slide. I'm not an angry drunk, or a problem drunk, or an obnoxious drunk. I just sort of start sliding down in the chair and pass out quietly.
Sometimes, I admit, I'll break briefly into tears about my long lost love or Super Bowl XII or Bigfoot or something, but usually I just slide.
