I want to stop

As the title says, I REALLY want to stop drinking, I just don't know how.

My mom was an alcoholic for 10 - 12 years of my childhood into teenage days, and I cant say I want to fall into her footsteps with 2 kids of my own now.

I dont drink everyday, but I do have 6 - 8 on Saturdays, which may not seem like a lot but it sure as hell does the next day, I just feel like I need something to do, and alcohol tends to fill that void.

I go to the gym when I can, and im also working 45 - 50hr weeks.

Any advice on how to get my brain to stop "wanting" it, would be much appreciated
