Alcohol consumption was already in decline before the massive increase in GLP-1 drug use. As someone who used Mounjaro, I think that's only the tip of the iceberg.
When on these drugs, you simply have no desire for such things, and I'm a beer and wine lover. Now that I've stopped, I'm slowly drinking again, but I feel my taste has changed.
I don't know if it was the drugs or the time that passed, but I simply can't drink or have the same desire as before (it could be my age, too, lol).
