Welcome to the forums,Sunflower, I had tried to stop drinking for good many times over a 40+ year period. This current attempt has been a success due to the support of the fine folks here. I hope you find the same.
In addition to the support here, the key for me was finally accepting that I would never be able to moderate my drinking. In my many other attempts I would fall into the trap of thinking "Gee, it wasn't that hard not the drink for xxx weeks/months, I must not be an alcoholic."
The earlier in your life that you accept the simple fact that you cannot moderate your drinking, the more fulfilling the rest of your life will be.
Ok, this old guy will stop preaching. Happy Holidays and Good Luck to you!
