I used Citaprolam for almost two years. And when I start thinking about that period, actually it was a period when I was holding control over stutter, and it was in that period I led several health seminars and projects connected to my work, and that included a lot of speaking in public. So maybe citalopram did help somewhat, because I remember now that i didn't have any big issues with stutter. I used Zoloft also, stopped with it last year, didn't notice any worsening in stutter when I used it, it was normal :) but I remember that with Zoloft my jaw was stiff as hell the first month and somewhat jingling. But that is a side effect of Zoloft.
