As another mentioned, exercise can do it. I find running to be meditative. Other than following the path (and sometimes just running) my mind is free to do whatever. No distractions like computers and TV. I usually run without music as well.

I also took up Brazilian jiu jitsu this year and I'm finding it helpful in another way. I'm not very good at it, so I have to stay focused during class and rolling trying to connect the dots. And it's sufficiently physically exhausting that once I'm done I'm ready to eat and then pass out. The next morning in feeling the soreness of my worn out muscles. Different but not totally unlike the hangovers described. The major difference being a sense of accomplishment and improvement letting me know that what I'm doing is worth the effort.

I run 5 days a week. Getting black out drunk is different. It's probably more like electroshock therapy. Think of it as running is de fragging your drive and getting blackout drunk is rebooting.
