Omnivore - More on misophonia

This request for help arrived a few days ago at my email address for my work in psychology. It pertains to misophonia, a brain disorder that makes some people, myself included, hypersensitive to certain sounds, especially while eating:

I know you’ve written about misophonia in the past. You said you’ve had it all your life but only recently learned that it’s a real disorder.
