It is so freeing, isn't it. There's been many occasions in the past couple of months where later in the evening I'll be fancying something sweet. Maybe a piece of cake or pie and so I just jump into the car and go to the all night grocery store and buy it. No worries about drinking and driving.
In addition to getting to work (well an hour late), I was able to do the entire shift without feeling tired, hungover, grumpy, sick (all those crappy things that go hand-in-hand with drinking).
