Ask HN: What benefits of quitting alcohol consumption?

I've decided to do a "dry" January and if I can do it, will try to extent to all of 2020.

I didn't drink often, not more than once a week. But it was usually a binge episode, having at least 10 drinks.

Has anybody stopped? What were the benefits? I am thinking that the reduction of stress on the body might lead to clearer thinking during work, etc.
