For many drinkers, suddenly stopping can be life threatening, causing seizures and convulsions.
I also stopped drinking, effectively cold turkey - but I wasn't a very heavy drinker, just a habitual one. However, I rejected AA as far too prescriptive in its approach.
For anyone reading this who is considering quitting alcohol I recommend r/stopdrinking on reddit, which is an incredibly friendly and supportive place where people practice and discuss a variety of methods.
For some heavy and consistent drinkers, they should check themselves into a hospital or clinic when they quit. But the vast majority of alcoholics will not develop delerium tremens when they quit. I personally worried about DT when I was drinking a six pack per day and used it as an excuse to never miss a day of drinking. I am probably not alone in my neurosis so telling people that they are likely to develop severe alcohol withdrawal is probably not a good way to help them to quit.
Surmounting all of this is very much like a lot of difficult tasks - often made more difficult by well-meaning people who want to point out all the difficulties you hadn't considered yet. What we need is more resources like: do you drink this much? Go to this clinic when you quit. Worried? Then quit sooner rather than later when you are drinking even more.
I think I agree with your intent and sentiment, and you're definitely right that people make excuses when it comes to quitting (and relapsing).
But IMO more often than not, we should't be flippant or dismissive about the excuses (for relapses or for continuing to use).
For some people, maladaptive coping—and all its consequences—is a cheap price to pay compared to facing a sober existence when unequipped to deal with it.
So even if they quit cold-turkey (or just quit), they won't necessarily improve their quality of life because they don't know why they got into addiction in the first place. However, going to support groups can help meet people. Those who struggle with similar root causes of their addiction tend to cluster as well, and that can (indirectly, and with a bit of luck) help identify root causes. That was what happened with me, and I'm forever grateful to support groups.
In my case I was an adult child of narcissistic parents (ACoNs)[1] and I struggled with C-PTSD[2] all my life (I self-misdiagnosed myself many times with depression, autism, younameit) and I'll live with it forever. In a twisted and perverse way, I think drug abuse and addiction—with all the indirect suffering they caused—also saved my life. If it weren't for drugs, literally wouldn't have had any coping mechanism whatsoever. So, in cases like mine quitting cold-turkey means that the withdrawal symptoms just compounded compounded with our emotional dysregulation.
Also I want to finish with this: I am really glad you managed to turn your life around and quit using. I'm happy that you took steps to improve your life, and as cheesy as it sounds: I'm proud of you! Thank you for sharing your story; I know talking about these things isn't easy.
