hello mj, welcome back
You left out a very important detail. And that is, Why do you drink? Why do you think you drink? What causes you to want to drink? Besides it being a 'bad habit' now, it has progressed to the stage of becoming a necessity for you to get along. I assume anyway.
There are a few things to discuss, or how to approach this. First of all, just quitting drinking without knowing why you started and continued drinking in the first place without addressing that issue will be a struggle. You'll need to deal with the psychological struggle (addiction) as well as the physiological addiction.
Then you must figure out how to get there. Can you take time away from work? A week? A month? A month away from your family?
If you can get a month, I recommend going to a 30 day rehab for you. Otherwise do a hospitalized detox and get quit drinking.
Many here quit drinking and use this site as a means of support. Look at the secular connections forum and learn what the "Big Plan" is. That may be up your alley.
