Welcome to SR Betterthiings. Great community with a ton of support here.
Your story sounds a lot like mine and others here. I'm in my early 40's, have a great wife, two beautiful kids, awesome and well paying job. Outside of my current sobriety, I have been drinking since around 18. My drinking evolved from enjoyable to life threatening throughout 20+ years. in 2007 I was diagnosed with fatty liver disease which is when I cut out all hard liquor and replaced it with beer and wine! Lol, its funny to ever see how I could rationalize that. I had trouble even catching a buzz after drinking a case of beer or a whole "box" of wine a few years later.
A couple years ago I started drinking earlier and earlier in the day. That led to drinking in the mornings on weekends and late mornings / early afternoons at the office. To the outside world, I was still functioning, but I new the truth and it was literally killing me.
I finally quit for good 253 days ago today.
You can do it, there are plenty of stories here that will give you hope.
I would have never made it without the SR community.
It helped me to read as many threads as possible early on and post often.
Best of luck, we are here to help!
