Hi,
I had no alcohol during 2006. A dry year, and this was no small feat for me considering that I had made it such a part of my life style over the last decade.
I am not an alcoholic, but I drank enough to question the binge drinker scenario, so, the solution was to put myself to the test.
The result was.... not a drop. I lost weight (15kg), got out of debt ($2000), got back into martial arts, quit smoking (11 months), achieved something worthwhile and motivated my friends and family.
My advice is to make a serious promise to yourself and have no room for excuses. No grog. Not a drop. Not even a cherry ripe.

And be loud and proud of it.
Even my hardest drinking mates wanted to see me succeed.
Ask yourself what your life would be like without alcohol, and dwell on the answer for a few days. This really helped me concrete the plan internally.
My sincerest best wishes and good luck.
