It’s different for everyone. My tolerance has been built over more than a decade. For me it was bad when it’s continuous for 3 or more days of heavy at night and a few drinks during the day to keep the hangover at bay. The quantity was somewhere around 1-1.5L 80 proof per day. I don’t do this anymore because of withdrawal. I could still function well enough and coffee helps with shakes. The depression can be bad, the horror nightmares are bad, mild hallucinating sometimes, and lots of sweating.

When I’m normal nightly drinking and no day drinking a normal night is 10 1.5oz full shots of 80 proof.

I do also stop occasionally and I know that I need to slow/stop or it will kill me. Also don’t see my number and use it to ignore your own problems. A lot of people die before they get to my quantities. For reference I’m a 185lb 5’11" dude and weirdly still am in almost half marathon shape. The exercise keeps some of the negative effects of drinking so much at bay. I also take B-vitamins every day.

I’ve used weed as risk mitigation in the past. It didn’t stick though, it makes me feel lethargic for days.
