I’m in IT and the number of meetings has increased exponentially over the years. I’ve gotten use to them now so it’s kind of desensitised me to daily meetings. I use to have to psych myself up for them but now it’s no big deal. Mind you, I’ve cut out caffeine, sugars and am taking anti anxiety meds, which is helping me a tonne too. Everyone is different, so you need to find what works for you and what exacerbates your stuttering.
