well not sure if I've " Learned" anything, but I can tell you a few things that have helped me.
Brief background, last summer, after some pretty good drinking through lockdown, I had my yearly checkup and had high ALT number. So I quit drinking and went back a month later and things were back to good. I made the decision to go ahead and keep it up.
I have tried to quit several times over the last 5 years, but I always end up slowly getting back to my old ways. The hardest part for me is that there are so many activities that I do that beer was associated with. Yard work? Have a beer, Grilling? Have a beer. Golf, have SEVERAL beers. you get the point. I had to learn to manage the triggers. For the most part that's all gone. I have my golf foursome, who I grew up with, who are also my drinking buddies. They have been really supportive and that's made it easier. I even went down to the local watering hole for some darts Wednesday night and the bartender just brings me a Diet Dr. Pepper without even asking if I want a beer.
My advice to those who are trying to quit, its like anything it will snowball the longer it goes. Also this is the first time I've "quit" without counting the days. Before I could always tell you how many days its been, now I only have a general idea. I know I quit sometime in June and with the exception of Election night I've been sober.
The benefits have been noticeable as well. I sleep SO MUCH better than before. I've saved a ton of money. My anxiety has improved as well as my overall health. I do miss that buzz you get from drinking, but not sure I could keep the drinking in moderation. So as I tell people, I don't know if I'll drink again, I just know I don't want to drink right now.
