One thing I can suggest is write down exactly how you feel about your alcohol problem. Include your physical and emotional feelings - anxiety, despair, sadness, nausea, etc. Go into as much detail as you can.
Then, when you feel tempted re-read your feelings and remind yourself just how you felt. I have done this and it has helped.
If you look at my posts you'll see that I have twice attempted to stay sober and capitulated. Now is my third time and I haven't had a drink so far this year.
Good Luck!
