Been on lexapro for three years. Similar experience to you. Stuttering is basically gone, but emotionally I am pretty blunted. To me it’s better than severe stuttering. It’s kind of a pick your poison type situation. I tried Wellbutrin for a day and couldn’t sleep, so I immediately stopped. Kinda wish I gave it more of a shot, but insomnia is the worst…wish I had something helpful to say, but just wanted to let you know you’re not alone!
