Hello my dear @erh.germany :)
I am glad you found the Rational Choice Model of Addiction an interesting one. It is controversial indeed, but I think it is mostly for those who are unable to put themselves in the position of the addict. Your need for hearing sounds of humans when you go to bed fascinates me as much as the explanation for it :D
I wish you a lovely Saturday.
All the best to you and to your family :)
