I found a medication-based program the NIH (National Institutes of Health) in the US. The drug is in phase 3 clinical trials right now. I know one stutterer who is 99% fluent now. The research is very promising. Check out this and other youtube videos about it. The researcher is Dr.Gerald Maguire who also stutters. It's amazing! https://youtu.be/uJTlCj-ZP2E https://youtu.be/uJTlCj-ZP2E Good luck, Sue
