I have also tried a lot, but unfortunately I have never had resounding success. I don't stutter very badly, but there are still situations where it is very annoying, depressing and the symptoms are bad! There are reports that medication against anxiety, schizophrenia, depressions could possibly help, but also with no resounding success. Recently there has been a drug, Ecopipam, which is being tested and might get a marketing authorization for stuttering if all goes well. More information: https://insideucr.ucr.edu/stories/2020/04/16/psychiatrists-review-treatment-stuttering I have no hope, because it is now the same as 10 or 15 years ago with the drug Pagaclone, there was a lot of talking, but then everything was stopped for "cost reasons". We, the stutterers, are not so valuable for the pharmaceutical industry and with our suffering not much money can be earned. But there are also reports that magnesium, vitamin B, l-theanine, St. John's wort, ashwagandha should help. No idea. I have already tried a lot, nothing has helped me personally! Unfortunately! All the best! Translated with www.DeepL.com/Translator (free version)
