I’m on Prozac and it’s helping a great deal with my social anxiety, which in turn helps me with my fluency too. I take Propanolol beta blocker for heavy speaking days such as interviews or presentations etc… helps a lot too. You will block less but it’ll help “soften the edges” and recover from a block easier. A GABA enhancer helps a lot too, which gives a similar effect to alcohol without the negative side effects of intoxication.
