Skin Deep (movie, 1989)

Hard-drinking novelist Zach Hutton spirals out of control after his wife and mistress both leave him. Alone and crippled by a bad case of writer's block, Zach slips in and out of casual relationships and one-night stands, while his drinking becomes more and more severe. With the help of a bartender and his therapist, Zach confronts his demons -- women and alcohol -- and rediscovers his writing voice.
