I only stutter when I go out for the night

I only stutter when I go out for the night So when I start drinking/ drunkI stutter and I can’t even speak certain words, like they just won’t come out of my mouth. I also stutter when it’s loud. So if there’s music playing or a dj, for starters it’s already hard to hear, so when I’m basically screaming to talk to someone and it gets bad too. And that’s not even when I’m drunk (but gets bad when I am). Last night when I was out I was fine but as soon as the dj started and the whole place was loud I had trouble speaking, but was fine beforehand. So basically I stutter and can’t speak words when I’m drunk and on top of the place whiny loud when I have to scream to talk.
