Also having a lot of trouble with this. My desk touches the desk of one of the worst gum chewers I’ve ever seen. Such a nice person, but I can’t help get infuriated every single day because she chews probably 2-4 pieces on a regular day. It’s one of the only situations where I feel hopeless, like there is no escape because I’m stuck at this desk. I wear headphones about 6 hours a day now, which is causing my ears to ring/is generally uncomfortable at the office. I just wish there was some kind of therapy I could go to but everything I’ve found online is about avoiding sound, not helping the condition. I just feel like it’s ruining my life!!!
