I was on the vodka thing at the end when I was drinking at work to stave off withdrawals while working.
There was always this one guy at work who didn't give a crap what anyone thought, and every time I would drink the vodka out in my car, he'd always call me out on it. People smell it. Some just may be too shy to bring it up for fear of an argument or whatever.
Also, I thought I was doing great while drinking. Hell I even landed the best job of my career (so far) while I was drunk. But then a month after starting said job, I started failing miserably at my career. Missing work because I was too hungover/still drunk, staying at home all day so I could drink all day... You get the picture.
I felt I was kicking ass at everything. Unfortunately I wasn't. I used all vacation time, had to have wife do everything around the house and take care of my 1 year old. It's something I will never go back to.
That was my experience with the whole vodka thing.
