I would argue you like the illusion of being in control, not that you are actually in control of anything.
Some of the greatest decisions of my life were made after a few drinks (Such as booking flights to other countries, hooking up with people, making lifelong friends). Sometimes our rational, thinking minds aren't as smart as they think they are, and a measured amount of unpredictability can make life better. Of course it's a double edged sword, and has a dark side, but things would be pretty uninteresting if you never had any regrets.
