Hey, I have never tried effaxor. Heck I don't evan know what that is 😂, but for the last two months I've been living on a simple rule explaned very detailed in a book called "The subtel art of not giving a fuck,,. If you want find it as an audiobook in youtube. I'm a stutter myself and I always got noxious when trying to speak with other people. To top it all of I'm currently living in Austria and still having problems with german. This made my stuttering even worse but then I just started to tell myself "I dont give a fuck" whenever I feel stressed out or angry at my stuttering not letting me say what I want to say. It may sound as a cliché but for me it works like a charm. Don't take this the wrong way, I still stutter but no so much and thoes words just tell me to not give a fuck if I make a mistake or not. Hope you find an answer to your question with the effaxor. Just wanted to share some experience. Stay positive and DONT GIVE A FUCK ABOUT IT 😊😊
