There are many ways that excessive alcohol damages nerves. Direct toxicity on nerves, vitamin depletion, liver and kidney damage which causes changes to biochemistry, stomach lining damage which causes gut infections (inflammatory responses). Unless you know for sure how alcohol damaged your nerves it's kind of like Russian roulette.

Also there is the fact that alcohol/drinking is enjoyable and you will always get pressured to drink more.

I can't drink at all due to my anxiety and the meds I take. But even though everyone knows I can't drink at every social event I am constantly getting pressured.
