Welcome!
I work the same shift you do. I found that not buying beer during the day keeps me from drinking during the week since I can't buy when I get out of work. So this shift has actually helped me. My problem was that I would drink heavily on the weekends and then start to detox during the week, only to go back to the heavy drinking.
I've been sober over a month and this is the first time I made it this long in 12 years. This site has helped me immensely. I'm here first thing when I get up and first thing when I get home from work.
