Honestly, I got tired of being tired. LFPs were normal but my cholesterol and stuff was off indicating that I was doing some kind of metabolic damage. I decided to say "fuck it" and told myself I'd do exactly one week of not drinking. The first weekend I woke up sober I was bored but I noticed that I wasn't tired, or extremely hungry, or anything. I just felt right.
Then I kept that feeling up, setting challenges along the way. "Use my sober time to my advantage". Improved blood work dramatically (back to normal), lost weight, and kept a bunch of good habits. Now, occasionally I'll indulge if I'm out or being social, but I've basically all but stopped drinking on anything remotely near as often as I did. I discovered a lot about myself by reflecting on what made me drink so much (I was much more social drunk) and how I can remedy that.
What works for me may not work for you. AA doesn't work for people, a lot of techniques don't work for people. There's no magic pill. You need to have a reason to do it, and a reason to stick with it. Something you can wake up every morning and remind yourself. Moreover, accept you will slip. It's not an end to your sobriety despite how AA treats it. You are human, what matters is that you learned from your slip and try your best not to do it again. To get to the point I am at I had go cold turkey for a year, and then slowly introduce it back and test myself. If I ever even come close to even two days a week now I'm back on the sober train for another year.
As for the experience of getting sober I never had to do DTs or anything. Though I did drink a lot. I found the first two weeks to be hardest, then the first two months, and then it got to be easy after that. In the first 2 weeks to 2 months you will face all sorts of challenges like having to cope with going to places you usually drink and not drinking, etc. If you can make it two months you have a good chance of sticking to it.
