I didn't realize Dry Drunk was an AA term. I have used it about myself when I quit in the past (I have never been a member of AA).
Anyway for me it was when I quit drinking but didn't enjoy sobriety. I just left a gaping hole in my life in which to be miserable.
This time I'm happy because I'm giving sober life a real chance. Lots to enjoy, contrary to what I thought!
