Thinking about purchasing cbd oil…

Thinking about purchasing cbd oil… I’m had looked into cbd oil and heard alot of PWS take it to relieve their anxiety and in return it helps their stutter a bit too. I just want something that can relieve that anticipatory feeling when ur about to stutter. I just want to hear ppl experiences with cbd in general and how it affected their stutter? Plus Is it safe to ingest? And how many mg you used to see an improvement in ur speech?
