I've cut all beer, and max one glass of wine. Drink plenty of whisky and bourbon though. The calories and carbs in a pint of beer are just not worth it. Light beer tastes like crap, and the craft/microbrewery beers are usually high calorie.
How can you be bored and work and still be too tired to do something after? I'm always looking forward to the end of the day, so I can go for a walk along the Thames with my girlfriend, maybe go for a drink or a quick dinner, catch a movie, workout together, etc.
