Weeks after I stopped drinking 24 years ago, I remember hearing one view was, alcoholics drink because they think they have to.
That was fairly close to my own view, once I drank due to addiction.
Substance addiction produces withdrawal discomfort, which the user seeks to avoid, keeping the cycle going.
So I quit just once, cold turkey. No detox, no coddling, just AA and gradually learning that I could do without, after all.
Physical discomfort minimal. Mental adjustment to change, plenty of challenge learning new thinking. IOW learning that I didn’t have to drink, and to be fine with that.
I was practically raised in an AA meeting.
The smell of percolated coffee and cigarettes is still with me to this day.
