The book Alcoholics Anonymous suggest 2 tests. One to test if we have physical craving (after we put a drink or two in our body) and another to test our mind, if we encounter the compulsion to drink.
Test A) We do not like to pronounce any individual as alcoholic, but you can quickly diagnose yourself. Step over to the nearest barroom and try some controlled drinking. Try to drink and stop abruptly. Try it more than once. It will not take long for you to decide, if you are honest with yourself about it. It may be worth a bad case of jitters if you get a full knowledge of your condition.
Test B) We think few, to whom this book will appeal, can stay dry anything like a year. Some will be drunk the day after making their resolutions; most of them within a few weeks.
