Have any of you successfully stopped by yourself?

I have been listening to some podcasts and one main theme is that you can't do this alone. Get out of your comfort zone, talk to other alcoholics, go to meetings, be honest with your loved ones about your problem, give in to a higher power etc.

My family knows I drink too much and that I am taking a break from drinking but they don't really know the extent of it. I have been pretty good at hiding the extent of my drinking. Throwing away beer cans at gas stations before getting home, sneaking into the pantry to take a couple pulls off a bottle while friends or family are in the other room, those types of things. I really do want to quit and mend all the damage I've done to my brain and body since I was a teenager.

I've tried quitting dozens of times over the past 5 years and have continually failed at those attempts. I'm beginning to think that maybe I need to face the music and be honest with my family but at the same time I don't really want my wife to know the extent of my drinking. I don't see how that would be good for her at all.

Any advice or insight from some of you who have been successfully sober?

Edit: Well holy shit thank you guys for making me not feel alone. I will be leaning on all of you hard.
