On May 12, 1973, Cheever awoke coughing uncontrollably, and learned at the hospital that he had almost died from pulmonary edema caused by alcoholism. After a month in the hospital, he returned home vowing never to drink again; however, he resumed drinking in August. Despite his precarious health, he spent the fall semester teaching (and drinking, both with fellow writer-teacher, Raymond Carver) at the Iowa Writers' Workshop, where his students included T. C. Boyle, Allan Gurganus, and Ron Hansen. As his marriage continued to deteriorate, Cheever accepted a professorship at Boston University the following year and moved into a fourth-floor walkup apartment at 71 Bay State Road. Cheever's drinking soon became suicidal and, in March 1975, his brother Fred, now virtually indigent, but sober after his own lifelong bout with alcoholism, drove John back to Ossining. On April 9, Cheever was admitted to the Smithers Alcoholic Rehabilitation Unit in New York, where he shared a bedroom and bath with four other men. Driven home by his wife on May 7, Cheever never drank alcohol again.
