I have quite a few triggers but chewing, slurping, gulping are the *worst*. I deal with it every school day (M-Th) and try my best just to plug that ear while she's eating. Sometimes it helps, though not for long. I swear she comes in to class with a full breakfast meal to eat. I've explained to her about misophonia but I think it's hard for those who don't suffer with it to understand and remember to be conscious about it.
