not sure on a psyciological level what causes it but it helps protect your teeth from the stomach acid. I’ve always used this thing you describe as an indicator, ie. its poasible to feel very sick but not actually throw up. however once my mouth goes ‘wet’ with saliva like you explained, thats the ‘point of no return’ where I 100% know I’m going to throw up no matter what happens next.
