Assuming benzodiazepines of some sort? That’s what I was prescribed for my stutter. Specifically Klonopin. But before Klonopin I was using Bromazolam, an RC benzo that you don’t need a prescription for. Just gotta know where to look. & By taking Bromazolam, I felt confident & fluent enough to get help & get a legitimate Klonopin script of my own. It didn’t cure me of course, but it sure helps a ton!
