All the same Scamy...in my field, we call it explanatory fiction...we all try to find a reason for the the things we do. Truth is, there is no such thing as a singular addiction gene. Also, there's a difference between causation and correlation: if 2 people had wrecks on the I-40 today after visiting DQ, anyone could say "ice cream causes car accidents" if they wanted to. NOT true, lol!
It's easy to blame our folks, past trauma, lovers, etc. for all our behavior, but that's victim mentality, and I can tell you ain't a victim.
Bottom line, you have ADD, you drink, you want to NOT drink, I assume, and starting here is a good place.
Love and hugs!
