Quitting is relatively easy. Staying stopped is the hard bit and where the real 'work' starts.
Dedicate your whole life to sobriety and your recovery from alcoholism and you stand half a chance. Sobriety has to be No1 priority above all else in your life. Anthing placed above sobriety will be lost anyway if you're an alcoholic.
Remember it's the first drink that does all the damage. One drink is too many and 100000 not enough.
You have to change your whole life and have total certainty that drinking will only lead you to jail, institutions or death. I know that is the reality for me.
SR is a great recovery resource and helps me stay sober. AA is also free and there are meetings everywhere.
Peace.
