Maybe it would help for people that do it involuntarily. Thats the only form of therapy to rid of this "behavior".

But since I'm enjoying doing it, I'd not consider doing that. Imagine you could eat your favorite food over and over again with almost the same taste as the first time you were eating it. Also there is no acid when I ruminate.. So no burning or whatsoever

However, since it is semi-voluntarily, I do have to force myself not ruminating when I'm around other people.
