This site has several posts on the time authors John Cheever and Raymond Carver spent drinking while in residence at the University of Iowa.
My favorite lines:
Because Cheever had no car, Carver provided transportation on their twice-weekly booze runs. They liked to arrive at the liquor store just as the clerk was unlocking for the day.
Now that’s alcoholism.
They were both excellent writers. Carver wrote great stories. I haven’t read his poems. Cheever wrote novels and stories. I would start with his stories.
Collections by both are part of the Library of America
