Alleged marital infidelity Francis Hartigan, biographer of Bill Wilson and personal secretary to Lois Wilson in her later years, wrote that in the mid-1950s Bill began a fifteen-year affair with Helen Wynn, a woman 18 years his junior that he met through AA.

According to Wilson, the session allowed him to re-experience a spontaneous spiritual experience he had had years before, which had enabled him to overcome his own alcoholism. Bill was enthusiastic about his experience; he felt it helped him eliminate many barriers erected by the self, or ego, that stand in the way of one's direct experience of the cosmos and of God. He thought he might have found something that could make a big difference to the lives of many who still suffered. Bill is quoted as saying: "It is a generally acknowledged fact in spiritual development that ego reduction makes the influx of God's grace possible. If, therefore, under LSD we can have a temporary reduction, so that we can better see what we are and where we are goingwell, that might be of
