I have one friend in particular who started a GLP-1 drug solely to assist in drinking less - she certainly does not need to lose any weight. It worked like a light switch for her and turned moderately problematic drinking into easily achieved light social drinking. No impact on appetite since she is on a very low dose.
I have had the same experience, even though I took it for weight loss to start with.
I do know that drinking can be downright unpleasant for me if I push through the aversion after my first drink and try to go for a few more. I have noticed a strong correlation to drinking and my blood sugar crashing rapidly afterwards while on Tirzepatide while wearing a glucose monitor.
A single cold beer on hot day with friends is still quite pleasant. Sitting in a bar for hours on end drinking heavily is simply downright uninteresting now before you get into any unpleasant side effects.
