abstainer

This term describes an individual who exercises willpower to avoid a specific indulgence, most commonly alcohol. It carries a connotation of discipline, moral conviction, or health-consciousness, suggesting a permanent or long-term commitment rather than a temporary diet. Because the word refers to a person, it follows standard countability rules. It is used to categorize people based on their habits of avoidance, often appearing in contexts related to temperance movements or medical restrictions.
