But I am curious: why not just moderate your drinking? The dose makes the poison. Yes, it is true that alcohol is bad for you, but so are many things. If you limit yourself, you can enjoy it on occasion without doing too much harm.
I personally don't see utility in having a hardline approach to alcohol. You only live once. If you want to crack open a bottle at Christmas, why not?
According to the WHO, there is no level of alcohol consumption that is good for the health.
OP sounds like he doesn't get anything out of drinking anymore, so I guess he doesn't even want to crack open a bottle for special occasions. He's realised he only lives once, so he kicked the booze.
As somebody who's never drunk, the only thing I think I've ever missed out on is the social lubrication element, but that just made me find people who are more like-minded.
Also, the point in the book alcohol explained, really stuck with me. One drink feels good for about half an hour, it's then replaced with feeling of anxiety unless you have another. It's like borrowing money with a high interest rate, except you are borrowing happines.
