I love ASMR and listen to it every single night except when I'm too tired for it and absolutely don't need it to fall asleep. Your article rings a bell in my head because I realize how addicted you can get to ASMR because it becomes a habit you associate with sleep very fast. To answer your question I do get the tingly sensation but once you have been watching too many videos you can become numb and not feel them anymore (except after a break from ASMR) which, when you think about it, really sounds like an addiction. I think taste plays a big role in what type of ASMR you enjoy because you have to be sensitive to it, I react to soft spoken but I completely hate mouth sounds (but some people are relaxed by them), so it's really up to each individual. I even start making ASMR videos on my Dtube channel because I am so passionate about it ^^ It's a big subject but I think there is a link between hypersensitivity and enjoying ASMR : if your nervous system gets overwhelmed by some noises other people don't react to you could become relaxed listening to some sounds other people don't get relaxed by, that's my understanding of the whole thing, and the reason why some people are not reactive to ASMR, I guess :)
