During her tenure as public relations officer of Citibank in the early 1970s, Sivasankariencountered many employees who were ostensibly sober during the day but heavily drinking at night parties. She was curious to know the reason behind their alcoholism, and wrote to Alcoholics Anonymous; after reading their pamphlets, Sivasankari saw alcoholism as a disease. She spent almost eight years working on the subject of Oru Manithanin Kathai, and interacted with many psychiatrists as part of her research. She claimed the story was based on the lives of many alcoholics, rather than a single individual. Sivasankari considered Oru Manithanin Kathai to be one of her most challenging novels to write.
