Over these many years in recovery the only meaning I have ever known for the term 'dry drunk' is someone who has only stopped drinking and done nothing to fix the underlying causes, ie the only thing that changes is the person is just not drinking.
Is that what you mean?
If is it, then I can tell you that AA sure helped me with that one. By working the steps, by going to meetings and learning all over again how to interact with others, I was learning new behaviors to replace the 'nasty' ones I had all those years I drank.
Since you asked:
Anyone know how to prevent it from happening?
Read this 'sticky' in this forum for different recovery programs that if worked can prevent a dry drunk from happening:
