Spiritual emptiness is often connected with addiction, especially by Christian-influenced addiction organizations and counsellors. Bill Wilson, the founder of Alcoholics Anonymous, argued that one of the impacts of alcoholism was causing a spiritual emptiness in heavy drinkers. In Abraham J. Twerski's 1997 book "Addictive Thinking: Understanding Self-Deception", he argues that when people feel spiritually empty, they often turn to addictive behaviors to fill the inner void. In contrast to having an empty stomach, which is a clear feeling, having spiritual emptiness is hard to identify, so it fills humans with a "vague unrest". While people may try to resolve this emptiness by obsessively having sex, overeating, or taking drugs or alcohol, these addictions only give temporary satisfaction. When a person facing a crisis due to feeling spiritually empty is able to stop one addiction, such as compulsive sex, they often just trade it in for another addictive behaviour, such as gambling or overeating.
