A word about sex relations.
Alcohol is so sexually stimulating to some people that they have over-indulged. Couples are occasionally dismayed to find that when drinking is stopped the drinker tends to be impotent. Unless the reason is understood, there may be an emotional upset.
Some of us had this experience, only to enjoy, in a few months, a finer intimacy than ever. There should be no hesitancy in consulting a doctor or psychologist if the condition persists. We do not know of many cases where this difficulty lasted long."
