Not really politically correct of me to say but sometimes a night of getting shitfaced with a good book or a video game, or a blog is just what the doctor ordered. It's not about having a good time it's about escaping reality if only for a brief moment. A vacation for the psyche that pays the price the next morning. A price I'm willing to pay - over and over.
I think you may be perfectly right, except I suffer from anxiety and alcohol is a depressant. Not a good mix.
