I wanted to answer before reading any other replies, so o wouldn’t be influenced. If I repeat something already said - I’m sorry.
I believe it is a mixture of the three. I believe I was born both to a family full of addicts and also with a brain that worked a little different then some other folks. I believe the way I was raised and the events that took place in my childhood left me with a constant desire to escape. I made choices on how to escape. It wasn’t magic for me like some people talk about. I didn’t love drinking as a teen. It actually scared me to feel that relaxed. I loved many drugs, but not drinking. As I got older I drank more and more while drugging. I eventually quit drugs and used alcohol as an everyday escape from reality fo another 10+ years. So I think MY answer to your question is yes, for a lot of different reasons I’m an alcoholic and I cannot safely consume alcohol.
