Thinking you need to define what "once a drunk" is.
Have I never been drunk? Yes.
Have I never been drunk over any lengths of time? No.
Never was drunk more than one day over months of time.
Yet I have been drunk many times.
I started kind of young by USA standards. Being in Germany in 1974 it was quite legal then for a 15 year old to be drunk. 😆
Heck, I even went there by myself, legally. And no one picked me up at the airport or train station either. 🤷🏻♂
Train station was under the airport in Frankfort. One transfer and a taxi ride got to my aunt's place, where I had to explain to my Aunt just who I was. In broken German. 😆
