For me the major miso-triggers are the sounds of people eating and the sounds of people typing -- which are wonderful triggers to have in the tech industry. :) Weirdly, these sounds only seem to set me off in an otherwise quiet environment. I can handle the sound of a thousand keyboards aflutter in a busy office. I cannot handle a totally quiet room with one person's typing in it. I can handle a group meal, but if I'm alone in a room, listening to one or two people eating, it drives me nuts.

There are also visual triggers, to make matters worse. For some reason beyond my understanding, I hate when people bounce their legs around in their seats, or tap their feet repeatedly on the floor. Drives me insane.

I've never had Tourette's, or any Tourette's-like symptoms, but I completely sympathize with those who do. My symptoms are similarly uncontrollable. I know they're weird, and I know that telling people about them generally pisses people off. So I am consigned to my own special hell, quietly mustering the mental energy to block these stimuli out in everyday life, knowing that nobody understands the problem nor has the slightest sympathy. Medical research barely takes the condition seriously, and a lot of doctors still refuse to acknowledge that it's real, and not some Freudian, neurotic symptom.

In a way, I feel like what someone with Tourette's must have felt like, back before Tourette's was medically or societally acknowledged. Every now and then, misophonia gets a cursory writeup in a major newspaper or magazine -- but even that coverage typically ends with some dismissive caveat, such as "Medical science doesn't currently acknowledge this as a legitimate condition." Well, I'm certainly not doing this for the fun of it. :)
