Dry mouth

I’m new to discovering this world and curious if this correlated:

I regularly have to present on zooms and I get insane dry mouth.

Even my jaw gets that annoying clicking sound which is audible to the audience.

I feel nervous presenting, it’s just something I will never get used to.

I try to take sips of water during transitions, I have a piece of gum tucked between lip.

Is there any hidden trick? Like celebs put Vaseline on their teeth? Idk

ChatGPT just told me to slow down and practice breath work 5 minutes before I start 🤷‍♀️ lol
