Drinking helped me when I was a shy teenager. I also thought drinking occasionally was keeping my mind healthy and helped me socialize (I.E find a random girl at a random bar). When I started a diet, I cut alcohol before anything else (highest glycemic index of what I was eating at the time). After a year, i was certain I would never drink again, bar some occasion (close family funerals). It improved my mental health by a lot, I can still socialize, except now I can actually care about the people I met and they're not random to me, and overall it's a better experience (except on sport nights).
