You're just stuck in a cycle and work is the place that society expects you to be normal. You are a logical person so you know that you must be normal at work for those few hours, also work is a distraction because you have responsibilities and tasks to carry out. Your mind is constrained for those few hours.
Yet when you leave work, that's the time that you're alone. You have all the time to reflect and think.. that's is when your mind is allowed to run free without the constraints of work. Alcohol indeed helps to loosen the mind more.
However, you wake up the next day realizing that the cycle starts again. You go through the cycle hoping to find a solution to break away from this cycle. Hoping that a miracle happens or something happens to wake you up from this nightmare. Until something does.. life will just be that cycle that you are experiencing.
