For me stopping completely is the answer. I've tried moderating for many years and even been sucessful much of the time. However, sooner or later there is always the instance when I drink more that I should or intended and there are negative consequences. Usually after that I am able to put together another good period of time of moderation or not drinking, but then it happens again. The cycle repeats over and over.
I finally reached a bottom and realized I needed help to stop completely. As has been mentioned if you want to stop there are many willing to help and you do not have to do it alone.
