Sobriety as a Working Musician

Hey all. I am a 32M and I work part time as a musician. As comes with the territory, a lot of performances and gigs take place in venues that serve alcohol. How can I improve my self control and be able to function as a musician without drinking?

I have had a problem with alcohol since the pandemic. Before that it really wasn't much more than a few beers and maybe a shot with my friends. Over time my lifestyle changed. Some of my coworkers are drinkers and I believe by hanging with them often after work I have developed terrible drinking habits. My go-to is always a beer and a shot combo. Or some sort of whiskey and ginger ale mixed drink. Alcohol addiction is a problem in my family, and I never thought it would affect me like this.

This lifestyle has become even more of a detriment to my career as a musician. Too often have I shown up to a gig with the mindset of no drinking and before I know it I am 3-5 drinks in before the show even starts. This of course affects my playing and the next day leaves me filled with regret and hungover.

Any musicians on here have advice for remaining sober at a gig when the presence of alcohol is sometimes overwhelming? I can't keep doing this to not just my bandmates, but myself. Alcohol does nothing to help me and I am angry that I can sabotage myself like this consistently.
