I quit drinking just a hair over six years ago. I quit turkey when I came to realize I was an a$$hole when drunk, I was getting drunk every night and waking every day perspiring booze, and I was wasting a large proportion of my limited lifetime being only partly tuned in to the life that was passing me by.
Best decision I ever made, took 30 years of hard drinking to make it. I thought it would be the hardest thing I ever did but it turned out to be the easiest, I have never looked back and stupid thoughts of taking a drink just don't enter my mind. I know in both my head and in my gut that drinking is hella bad for me and one drink will pull me into the abyss. So it's as easy as pie for me to decide not to take a drink, and my brain has moved on to other pursuits.
I know it is almost never this easy for most people and consider myself lucky as hell it was this easy for me to escape my prison. My dad is a recovered alcoholic (> 45 years sober) and needs AA, which is what saved him.
I had tried to quite a few times over the years after particularly bad drunks, usually when I'd done something really shameful to somebody close to me. I don't know what switch finally got flipped in my brain, but in my mid-40s my time was right. All the best to you and the others on here hoping/trying/wishing to quit. I hope some of you have my luck, and some of you also have my dad's luck, or some other version of your own luck. Drinking is not bad for everyone, but for those it is bad for, it can be a true hell.
