If you haven't listened to the This American Life (www.youtube.com) segment on it then you should. Listening to the show when it's compared to a porn addiction, even though she emphasizes that it's not like porn at all, I still have a hard time being... well empathetic isn't really the best word but its close. It's still an addiction for sure, one that takes up a vast amount of a persons day in order to seek pleasure and relief from anxiety and stress.
At any rate, I definitely do not have ASMR as far as I can tell after listening to some of this stuff. Though to some degree I have on occasion had the sensations described, sort of.
