I quit listening to talk radio because nearly all of it is politically inflammatory, which I think was contributing to the problem before.
I have been youtubing stuff like old Larry the cable guy shows, but that is not a longterm solution.
A friend of mine who successfully quit drinking several years ago began listening to nothing but gospel music. I think largely for the reasons we are discussing. While I have nothing against gospel music at all, and listen to it sometimes, I don't see that as a longterm solution either.
Maybe Dee is right and there will eventually be a desensitization effect.
