Imbalance of Emotion
Alcoholics tend to experience frequent mood swings and can’t keep one emotion for a long time. Mental dysfunction will flare up in alcoholics if they are unable to drink. If you feel the disruption of your emotional balance when you don’t drink, you’re likely to develop an addiction.
Defensiveness
If you have to defend your drinking to someone, as long as someone is reasonable, you can be an alcoholic very well. No responsible drinker should argue about how much he or she has consumed. It is even more indicative of a problem if you have to defend your sobriety while drunk.
