Ancedote, I didn't feel addicted to a drug. I would go a day or few without having it.
This was until someone claimed I was addicted. As soon as I heard that, I did research to learn if I was actually addicted to the drug. Like a switch, I stopped having multi day breaks. Multi day breaks wasn't what addicts do.
I'm off everything now, but I do wonder if simply learning about addiction triggered my brain to have the suggested symptoms.
