Why does your saliva go watery before you vomit?

I couldn't help but notice when I feel like vomiting is imminent, my saliva goes super watery in consistency, and was wondering the function behind it ^_^

It's part of the reflex. The parotid gland squirts a load of watery (serous) saliva into your mouth. This not only lubricates the vomits' path outwards, it also helps to alleviate some of the acidity of your extremely acidic stomach acid to minimise damage.
