It was a difficult hurdle for me to get past a weekend. That was where I always picked up again. I'd be good all week, but then Friday night I would drink.
I finally managed to get through the weekends when I realized that I needed to change my routine. I also humiliated myself to the point that I didn't just forget how bad alcohol was for me. I had to keep reminding myself of these things. Find alternative activities that don't involve alcohol (movie, gym, walking, sports, etc).
I made lists too. I listed pros and cons of alcohol in my life. I kept this somewhere I could easily access it when I felt like I wanted to drink. That way if I couldn't think of the reasons not to drink, I had the list somewhere nearby to remind me.
