Hi.
The “definition” I got years ago is a sober acts and reacts to life in a healthy manner mentally and emotionally.
A dry drunk is a person though not drinking acts in the same situation as if they were still drinking.
Even after a lot of sober years I have occasion to act like a dry drunk, I feel it’s some sort of a temporary chemical change. It might happen after a short rest period and I’ll awaken like a mean bear and wonder where the heck did that come from as the period before resting things seemed fine.
BE WELL
