Very strong medication does seem to help with stuttering

Very strong medication does seem to help with stuttering Around October, I had a stomach tube insertion for my developed acid reflux that I started getting around the beginning of 2022. So to speak, they used this gas that made me fall asleep until I finally woke up after the procedure, right away, I felt incredibly different, like as if something was lifted, and I was totally calm. The weirdest part was that I was able to speak fluently, I was in a very good mood to add on top of that. For about a half an hour I felt like a totally different person, it was like I never had a stutter in the first place. Eventually it came back as soon I was able to walk properly again and when the feeling completely wore off, i’ve seen a lot of incidents where people have taken a specific drug or medication and their stutter mostly disappears and achieve 90% fluency, depending on the person. So that makes me wonder, is there a connection here
