I quit drinking alcoholic beverages back in 2010. Being a non-drinker predates my turning MGTOW.
First, this is not a "you must be a non-drinker or you're evil" post. I'm not saying that anyone else is somehow obligated to give up alcohol. I'm only saying that it's worked for me, and for some other people. I'm saying it's a viable option.
Alcohol was fucking over my life. I was in a job I hated, and wasn't anywhere near a kind of life that I actually wanted. I never had any problem with DUIs. If I went out to a club to see musical or comedy performances, I never consumed a drop. I could have been pulled over every day and they never would have gotten me on any drinking and driving. I never did that.
What I did do, was I would get off work and feel like shit about the life that I hated, so I would go to the grocery store and buy a bunch of German- or Dutch-imported beer. Then I would take it home and watch some show or movie and get plastered. I got real sick and tired of having to get through my work day at the hated job while hung over.
One day I was feeling like crap at work due to a hangover, and I just decided I wasn't doing that any more. I quit alcohol. I didn't need rehab, fortunately; I just quit. I went to a few AA meetings, and I talked with my therapist. It wasn't as hard as it is for some people because I wasn't as far down the path to addiction as some. Some people develop a physical dependence on alcohol. For that severe a case, you can't just quit. You need detox and rehab.
But anyway, at first I craved the beers, but it didn't take that long for cravings to go away. Then I noticed better control over my life. The thing that had really sucked was I realized I was out of control. I HAD to drink at the end of a work shift when I wasn't feeling so great. And on that really bad hungover day, I realized I would never reach any of my goals if I didn't quit doing this shit.
So I quit. It was over a decade ago. I have achieved my goal of learning to speak fluent French. I also broke into the tech industry, and now enjoy my job much more than the retail crap I was doing back then. I've also been re-learning to play the guitar.
One of my goals upon quitting alcohol was to spurt off my jizz into a woman's snatch. I did do that, but since turning MGTOW, I've dumped that from my list of goals.
Again, I'm not saying that everyone has to do this, only that it's an option. If you notice alcohol causing more problems in your life than it's worth, you're fully capable of throwing alcohol out of your life. If you want to. It's your choice.
Alcohol was interfering in my ability to build a good life, so throwing it's ass out was worth it for me.
