the mouth sweats 

The feeling you get in your mouth when you've had to much to drink and you take one more shot, and your mouth starts salivating like you're about to throw up.

"Take one more you bitch, last shot of the night."
"I can't drink any more whiskey, that last shot have me the mouth sweats."

I'm about to throw up, that shot gave me the mouth sweats.
