This thing is so hard. I’m 77f and although I’ve tried most of the over-the-counter things as well as many of the prescribed antipsychotics nothing exceptional one, Abilify, had ANY effect. I actually totally stopped stuttering for 2 years although the had the quit the Abilify after 8 months because I never could sleep! That was two years ago and im very seriously considering trying it again. I do have a therapist here who will prescribe it again. (maybe) Dr.Maguire is amazing. He is currently working on specific drugs which are in clinical trials. Sadly, everyone is unique. Not every or any drug will work for everyone. If I can help further please let me know. Sue
