Bill having a nasty problem with delusions of grandeur. Bill Wilson's life in the period of 1930 to 1934 was like this:

His hangovers and hallucinations were becoming more frequent. He panhandled and stole from his wife's purse. He would ride the subways for hours after buying a bottle of bootleg gin, talking gibberish to frightened strangers. He threw a sewing machine at Lois and stormed around their house in Brooklyn kicking out door panels. She called him a "drunken sot." He would be sober for days and weeks and then settle into bottomless bingeing. He barely ate. He was forty pounds underweight. His dark, withdrawn periods alternated with delusions of grandeur. Once he told Lois that "men of genius" conceived their best projects when drunk.
Getting Better Inside Alcoholics Anonymous, Nan Robertson, pages 42-43.
Nan Robertson implied that Bill Wilson's delusions of grandeur disappeared after he quit drinking, but Bill's writings do not show that. Neither does the rest of the literature about Alcoholics Anonymous.
