N-acetylcysteine (NAC) is a harmless (EDIT: please check at least https://en.wikipedia.org/wiki/Acetylcysteine for possible side effects) compound which protects your liver, you can buy after searching like for 10 seconds
I ve been taking it for a week (1 pill, 600mg per day) before noticing that drinking doesn’t do anything. Went to a party, drank 3 pints of beer, one after another, with absolutely zero effect. Usually, just 1 pint is enough to get socially talkative, 3 pints of beer i am supposed to be very obviously drunk.
Another time, drank a third of a bottle of wine (at my place, so it cannot possibly be watered down), the only effect was nausea (which never happened before), again, zero drunk-ness effect.
Now, depending on people that anti-alcohol protection might be an advantage or drawback. I just found it interesting, so sharing here
Edit: as one comment points out: https://pubmed.ncbi.nlm.nih.gov/30019966/


Does it protect the liver or does it reduce the alcohol consumption?
It does protect the liver. That’s the whole point. Check the article
No, that is not what the article is about. It is about reduced consumption.
NAC does protect the liver, that a fact. It’s also used to treat paracetamol overdose which otherwise, would kill the liver. I don’t know how to interpret that sentence you cited
