Aside from having better sleep than at any other point as an adult, I truly enjoy the activities I partake in just as much, if not more, than when I still paired them with alcohol. It took about 6 months to stop feeling like I was missing out, and now I feel like everyone else is.
Anxiety in general is noticeably lower (this was a huge windfall for me when the pandemic started).
Enjoyment of conversation, food, setting, all seem richer and doesn't flag as quickly once the alcohol is metabolized.
The end of the drinking activities don't leave me sleepy or craving bad food. I can go home and read a book or get some work done.
General reduction in workout recovery time and aches and pains.
Holidays are way easier to get through.
The only drawbacks have been the situations you discover are entirely dedicated to consumption, e.g. dive bars, beer gardens, work holiday parties and happy hours. Without having dulled your senses adequately, some of these things tend to be only loud, smelly, or without much to offer besides booze and banter.
