Im on Lexapro and Diazepam for my stutter. Lexapro and Paxil both helped my stuttering immensely. I switched to Lexapro because sexual problems with Paxil. Diazepam is a wonderdrug for stuttering but I have to be careful. I hate that I have to take Benzos a couple times a week because of my stupid stutter tho. Im 80% fluent on 10mg Valium. Before Paxil and Lexapro I could barely speak or look someone in the eyes.
