Ketamine Therapy worked for mild Tourette's. Can it work for mild stuttering?

Ketamine Therapy worked for mild Tourette's. Can it work for mild stuttering? I think it would have worked even better if I had speech therapist counseling coupled with the ketamine therapy that I took for other reasons. But I noticed a side effect of my Tourette's was quieting down significantly. Also, some of my minor OCD compulsions also were able to be controlled, but eventually came back. I have read that Tourette's is similar to stuttering in terms of the brain regions affected. I wanted to know if anyone in this community has tried ketamine and seen any type of change.
