Not going to lie, in my case, yes, I see difference, a lot in fact. But keep in mind that these type of meds are really addictive and if they work for you, your stutter can get you hooked on them; you get used to stutter less when you take these pills, and more anxiety than normal will come when you try to talk without being on that medication, making you stutter more and taking another dose. An easy and fast way to get addicted. Be careful
