Depends on the night now.
In my 20s I could drink a lot. Too much.
Now it’s low, probably 10-15 and I’m looking to puke the next day.
Oddly enough, if I have 5-7 drinks the night before and sleep I’m fine the next day. If I drink again that next day, I can drink forever it seems.
Short answer, much less than before haha.
"The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents... some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the light into the peace and safety of a new Dark Age."
