Disclaimer: I am not a doctor. This post is based on my experiences with the intention of formulating my thoughts into a coherent essay and, hopefully, to start a dialogue with others about this.
According to a Google search the definition of drunk is "affected by alcohol to the extent of losing control of one's faculties or behavior". This definition seems obvious- drunk is when one drinks too much and dry is when one is sober. However, what then is a dry drunk? A dry drunk is someone who is not actively drinking/drugging but has the same thoughts, feelings and actions as an alcoholic.
People who are not addicts/alcoholics do not believe drugs or alcohol will solve their problems. For most, the thought does not cross their minds. Dry drunks feel alcohol/drugs is a solution to living a content life. If one is not currently using any substance, but finds comfort in the thought that if only they did they will be at peace, their issues solved and live a good life, it is very likely this person is a dry drunk.
In Alcoholics Anonymous they mention the concept of "RID" (restless, irritable and discontent) to describe those who are living without using but are not doing what is "suggested" (a.k.a. required) to maintain a peaceful, sober life. These people often end up falling into the hellish cycle of addiction.
Would you blame them? How long can one go feeling so much "RID" and deal with life on life's terms? Eventually, this dry drunk will turn to what makes sense to him to cure those uncomfortable feeling within- drugs/alcohol.
Before one ever becomes a diagnosed alcoholic or drug addict, they plan to use. I remember when I was 17 drinking a cocktail at a family event. The feelings of being ugly, weird, less than, and lonely disappeared. The sky was so blue. I looked like a fashion queen. I could not stop smiling. I was funny. Right then I planned that when I was on my own one day, I would drink this every morning so that every day would be great. I had found my solution! I drank and drank that evening and do not remember the rest of the night. It was years until I became a round the clock drinker. A depressed alcoholic who needed the drink to not be sick. In between the time I planned my drinking career and become an alcoholic, I was a dry drunk. Many try therapists, religion, relationships, food, career, acupuncture and more to get rid of that feeling they feel in their gut. A hole in their chest that can not be filled. Many describe feeling a void they can not shake off, perpetual unhappiness and an obsession or craving for something- anything- to get rid of "this".
Dry drunks who acknowledge they are potential problem drinkers or drug users may feel uncomfortable seeking help or going to AA meetings. They may feel that they do not belong. Feelings are not facts. If they are restless, irritable and discontent and are obsessed with the idea of drugs/alcohol as a solution they are no different than any other alcoholic/addict.
In conclusion, dry drunks have the same thoughts and tendencies as alcoholics/addicts before they relapse. It is only a matter of time until the dry drunk crosses the line and becomes a drunk. There is so much pain in suffering an addiction. It is best to get support and help if you feel you are heading there. Remember, rock bottom is when you stop digging.
