Yea. I was going through a rough patch in my life which caused an abnormal amount of anxiety. Also could have been long covid… not sure. But anyways. The anxiety was curbing my fluency, and even basic sentences were tough to get out. I go to a doctor and get prescribed Prozac, and less than 1 month later I have never been more fluent in my life. I still stutter obviously, but it feels minimal compared to what I’ve had my whole life. It’s only been about 7 months, but it feels great. Edit: this is my own personal experience. Please talk to your doctor about taking Prozac. I have no scientific evidence to back this up what so ever.
