I am generally against advising pot or alcohol for fluency. But if it's for purposes of recording a video, and you're not going to send it without reviewing it while sober, I don't see the harm. I'd also advise just powering through several recordings. Go ahead and stutter. But do the entire video. I don't care if the three minute video ends up being six or eight. Get through it a couple times. Keep these videos. You may never show them to another soul. Someday you may find value looking at them as you've moved along your journey towards fluency.
