I know you were asking victor, but in my case ...
I have gone from borderline morbidly obese to a healthy size (60+ pounds loss). That is not entirely due to cutting out booze because I have also been doing a 5:2 fasting diet. If I were still drinking, I think my weight gain would have stopped, but I wouldn't have lost much.
I don't have a hangover every day!
I feel less depressed.
I have more energy.
Most importantly - I haven't died!
(As most people on CC must know by now, I nearly did a couple of years ago and alcohol abuse was likely to have been a big contributing risk factor.)
